     *
     * A service that applications can use to interact with a browser's URL.
     *
     * Depending on which {@link LocationStrategy} is used, `Location` will either persist
     * to the URL's path or the URL's hash segment.

     * trailing slash:
     * - `/my/app/user/123` is normalized

     * Date-time format that depends on the locale.

     * The date-time pattern shows how to combine separate patterns for date (represented by {1})
     * and time (represented by {0}) into a single pattern. It usually doesn't need to be changed.
     * What you want to pay attention to are:
     * - possibly removing a space for languages that don't use it, such as many East Asian languages
     * - possibly adding a comma, other punctuation, or a combining word
     *
     * For example:
     * - English uses `{1} 'at' {0}` or `{1}, {0}` (depending on date style), while Japanese uses
     *  `{1}{0}`.
     * - An English formatted date-time using the combining pattern `{1}, {0}` could be
     *  `Dec 10, 2010, 3:59:49 PM`. Notice the comma and space between the date portion and the time
     *  portion.
     *
     * There are four formats (`full`, `long`, `medium`, `short`); the determination of which to use
     * is normally based on the date style. For example, if the date has a full month and weekday
     * name, the full combining pattern will be used to combine that with a time. If the date has
     * numeric month, the short version of the combining pattern will be used to combine that with a
     * time. English uses `{1} 'at' {0}` for full and long styles, and `{1}, {0}` for medium and short
     * styles.

     * <b>Important:</b> The characters `.` `,` `0` `#` (and others below) are special placeholders;

     * You must NOT "translate" the placeholders; for example, don't change `.` to `,` even though in
     * your language the decimal point is written with a comma. The symbols should be replaced by the
     * local equivalents, using the Number Symbols for your language.
     *

     *
     * | Symbol | Meaning |
     * |--------|---------|
     * | . | Replaced automatically by the character used for the decimal point. |
     * | , | Replaced by the "grouping" (thousands) separator. |
     * | 0 | Replaced by a digit (or zero if there aren't enough digits). |
     * | # | Replaced by a digit (or nothing if there aren't enough). |
     * | ¤ | This will be replaced by a currency symbol, such as $ or USD. |
     * | % | This marks a percent format. The % symbol may change position, but must be retained. |
     * | E | This marks a scientific format. The E symbol may change position, but must be retained. |
     * | ' | Special characters used as literal characters are quoted with ASCII single quotes. |

     * - `string` - the CSS classes listed in the string (space delimited) are added,
     * - `Array` - the CSS classes declared as Array elements are added,
     * - `Object` - keys are CSS classes that get added when the expression given in the value
     *              evaluates to a truthy value, otherwise they are removed.

     * Instantiates a single {@link Component} type and inserts its Host View into current View.
     * `NgComponentOutlet` provides a declarative approach for dynamic component creation.
     *
     * `NgComponentOutlet` requires a component type, if a falsy value is set the view will clear and
     * any existing component will get destroyed.
     *
     * ### Fine tune control
     *
     * You can control the component creation process by using the following optional attributes:
     *
     * * `ngComponentOutletInjector`: Optional custom {@link Injector} that will be used as parent for
     * the Component. Defaults to the injector of the current view container.
     *
     * * `ngComponentOutletContent`: Optional list of projectable nodes to insert into the content
     * section of the component, if exists.
     *
     * * `ngComponentOutletNgModuleFactory`: Optional module factory to allow dynamically loading other
     * module, then load a component from that module.
     *
     * ### Syntax
     *
     * Simple
     * ```
     * <ng-container *ngComponentOutlet="componentTypeExpression"></ng-container>
     * ```
     *
     * Customized injector/content
     * ```
     * <ng-container *ngComponentOutlet="componentTypeExpression;
     *                                   injector: injectorExpression;
     *                                   content: contentNodesExpression;">
     * </ng-container>
     * ```
     *
     * Customized ngModuleFactory
     * ```
     * <ng-container *ngComponentOutlet="componentTypeExpression;
     *                                   ngModuleFactory: moduleFactory;">
     * </ng-container>
     * ```

     * The `NgForOf` directive instantiates a template once per item from an iterable. The context
     * for each instantiated template inherits from the outer context with the given loop variable
     * set to the current item from the iterable.
     *
     * ### Local Variables
     *
     * `NgForOf` provides several exported values that can be aliased to local variables:
     *
     * - `$implicit: T`: The value of the individual items in the iterable (`ngForOf`).
     * - `ngForOf: NgIterable<T>`: The value of the iterable expression. Useful when the expression is
     * more complex then a property access, for example when using the async pipe (`userStreams |
     * async`).
     * - `index: number`: The index of the current item in the iterable.
     * - `first: boolean`: True when the item is the first item in the iterable.
     * - `last: boolean`: True when the item is the last item in the iterable.
     * - `even: boolean`: True when the item has an even index in the iterable.
     * - `odd: boolean`: True when the item has an odd index in the iterable.
     *
     * ```
     * <li *ngFor="let user of userObservable | async as users; index as i; first as isFirst">
     *    {{i}}/{{users.length}}. {{user}} <span *ngIf="isFirst">default</span>
     * </li>
     * ```
     *
     * ### Change Propagation
     *
     * When the contents of the iterator changes, `NgForOf` makes the corresponding changes to the DOM:
     *
     * * When an item is added, a new instance of the template is added to the DOM.
     * * When an item is removed, its template instance is removed from the DOM.
     * * When items are reordered, their respective templates are reordered in the DOM.
     * * Otherwise, the DOM element for that item will remain the same.
     *
     * Angular uses object identity to track insertions and deletions within the iterator and reproduce
     * those changes in the DOM. This has important implications for animations and any stateful
     * controls (such as `<input>` elements which accept user input) that are present. Inserted rows can
     * be animated in, deleted rows can be animated out, and unchanged rows retain any unsaved state
     * such as user input.
     *
     * It is possible for the identities of elements in the iterator to change while the data does not.
     * This can happen, for example, if the iterator produced from an RPC to the server, and that
     * RPC is re-run. Even if the data hasn't changed, the second response will produce objects with
     * different identities, and Angular will tear down the entire DOM and rebuild it (as if all old
     * elements were deleted and all new elements inserted). This is an expensive operation and should
     * be avoided if possible.
     *
     * To customize the default tracking algorithm, `NgForOf` supports `trackBy` option.
     * `trackBy` takes a function which has two arguments: `index` and `item`.
     * If `trackBy` is given, Angular tracks changes by the return value of the function.
     *
     * ### Syntax
     *
     * - `<li *ngFor="let item of items; index as i; trackBy: trackByFn">...</li>`
     *
     * With `<ng-template>` element:
     *
     * ```
     * <ng-template ngFor let-item [ngForOf]="items" let-i="index" [ngForTrackBy]="trackByFn">
     *   <li>...</li>
     * </ng-template>
     * ```
     *
     * ### Example
     *
     * See a [live demo](http://plnkr.co/edit/KVuXxDp0qinGDyo307QW?p=preview) for a more detailed
     * example.

    /**
     * Conditionally includes a template based on the value of an `expression`.
     *
     * `ngIf` evaluates the `expression` and then renders the `then` or `else` template in its place
     * when expression is truthy or falsy respectively. Typically the:
     *  - `then` template is the inline template of `ngIf` unless bound to a different value.
     *  - `else` template is blank unless it is bound.
     *
     * ## Most common usage
     *
     * The most common usage of the `ngIf` directive is to conditionally show the inline template as
     * seen in this example:
     * {@example common/ngIf/ts/module.ts region='NgIfSimple'}
     *
     * ## Showing an alternative template using `else`
     *
     * If it is necessary to display a template when the `expression` is falsy use the `else` template
     * binding as shown. Note that the `else` binding points to a `<ng-template>` labeled `#elseBlock`.
     * The template can be defined anywhere in the component view but is typically placed right after
     * `ngIf` for readability.
     *
     * {@example common/ngIf/ts/module.ts region='NgIfElse'}
     *
     * ## Using non-inlined `then` template
     *
     * Usually the `then` template is the inlined template of the `ngIf`, but it can be changed using
     * a binding (just like `else`). Because `then` and `else` are bindings, the template references can
     * change at runtime as shown in this example.
     *
     * {@example common/ngIf/ts/module.ts region='NgIfThenElse'}
     *
     * ## Storing conditional result in a variable
     *
     * A common pattern is that we need to show a set of properties from the same object. If the
     * object is undefined, then we have to use the safe-traversal-operator `?.` to guard against
     * dereferencing a `null` value. This is especially the case when waiting on async data such as
     * when using the `async` pipe as shown in following example:
     *
     * ```
     * Hello {{ (userStream|async)?.last }}, {{ (userStream|async)?.first }}!
     * ```
     *
     * There are several inefficiencies in the above example:
     *  - We create multiple subscriptions on `userStream`. One for each `async` pipe, or two in the
     *    example above.
     *  - We cannot display an alternative screen while waiting for the data to arrive asynchronously.
     *  - We have to use the safe-traversal-operator `?.` to access properties, which is cumbersome.
     *  - We have to place the `async` pipe in parenthesis.
     *
     * A better way to do this is to use `ngIf` and store the result of the condition in a local
     * variable as shown in the the example below:
     *
     * {@example common/ngIf/ts/module.ts region='NgIfAs'}
     *
     * Notice that:
     *  - We use only one `async` pipe and hence only one subscription gets created.
     *  - `ngIf` stores the result of the `userStream|async` in the local variable `user`.
     *  - The local `user` can then be bound repeatedly in a more efficient way.
     *  - No need to use the safe-traversal-operator `?.` to access properties as `ngIf` will only
     *    display the data if `userStream` returns a value.
     *  - We can display an alternative template while waiting for the data.
     *
     * ### Syntax
     *
     * Simple form:
     * - `<div *ngIf="condition">...</div>`
     * - `<ng-template [ngIf]="condition"><div>...</div></ng-template>`
     *
     * Form with an else block:
     * ```
     * <div *ngIf="condition; else elseBlock">...</div>
     * <ng-template #elseBlock>...</ng-template>
     * ```
     *
     * Form with a `then` and `else` block:
     * ```
     * <div *ngIf="condition; then thenBlock else elseBlock"></div>
     * <ng-template #thenBlock>...</ng-template>
     * <ng-template #elseBlock>...</ng-template>
     * ```
     *
     * Form with storing the value locally:
     * ```
     * <div *ngIf="condition as value; else elseBlock">{{value}}</div>
     * <ng-template #elseBlock>...</ng-template>
     * ```
     *

     * In other words:

     * - you define inner views inside the `NgSwitch` and place a `*ngSwitchCase` attribute on the view
     * root elements.
     *
     * Elements within `NgSwitch` but outside of a `NgSwitchCase` or `NgSwitchDefault` directives will
     * be preserved at the location.
     *
     * The `ngSwitchCase` directive informs the parent `NgSwitch` of which view to display when the
     * expression is evaluated.
     * When no matching expression is found on a `ngSwitchCase` view, the `ngSwitchDefault` view is

     * In javascript, only the components specified will be respected (not the ordering,

     * Timezone of the formatted text will be the local system timezone of the end-user's machine.
     *
     * When the expression is a ISO string without time (e.g. 2016-09-19) the time zone offset is not
     * applied and the formatted text will have the same day, month and year of the expression.
     *
     * WARNINGS:
     * - this pipe is marked as pure hence it will not be re-evaluated when the input is mutated.
     *   Instead users should treat the date as an immutable object and change the reference when the
     *   pipe needs to re-run (this is to avoid reformatting the date on every change detection run
     *   which would be an expensive operation).
     * - this pipe uses the Internationalization API. Therefore it is only reliable in Chrome and Opera
     *   browsers.
     *
     * ### Examples
     *
     * Assuming `dateObj` is (year: 2010, month: 9, day: 3, hour: 12 PM, minute: 05, second: 08)
     * in the _local_ time and locale is 'en-US':

     * emitted. When a new value is emitted, the `async` pipe marks the component to be checked for
     * changes. When the component gets destroyed, the `async` pipe unsubscribes automatically to avoid
     * potential memory leaks.
     *
     *
     * ## Examples
     *
     * This example binds a `Promise` to the view. Clicking the `Resolve` button resolves the
     * promise.
     *
     * {@example common/pipes/ts/async_pipe.ts region='AsyncPipePromise'}
     *
     * It's also possible to use `async` with Observables. The example below binds the `time` Observable
     * to the view. The Observable continuously updates the view with the current time.
     *
     * {@example common/pipes/ts/async_pipe.ts region='AsyncPipeObservable'}

     *
     * Formats a date value according to locale rules.
     *
     * Only the `en-US` locale data comes with Angular. To localize dates
     * in another language, you must import the corresponding locale data.
     * See the [I18n guide](guide/i18n#i18n-pipes) for more information.
     *
     * @see `formatDate()`
     *
     *
     * @usageNotes
     *
     * The result of this pipe is not reevaluated when the input is mutated. To avoid the need to
     * reformat the date on every change-detection cycle, treat the date as an immutable object
     * and change the reference when the pipe needs to run again.
     *
     * ### Pre-defined format options
     *
     * Examples are given in `en-US` locale.
     *
     * - `'short'`: equivalent to `'M/d/yy, h:mm a'` (`6/15/15, 9:03 AM`).
     * - `'medium'`: equivalent to `'MMM d, y, h:mm:ss a'` (`Jun 15, 2015, 9:03:01 AM`).
     * - `'long'`: equivalent to `'MMMM d, y, h:mm:ss a z'` (`June 15, 2015 at 9:03:01 AM
     * GMT+1`).
     * - `'full'`: equivalent to `'EEEE, MMMM d, y, h:mm:ss a zzzz'` (`Monday, June 15, 2015 at
     * 9:03:01 AM GMT+01:00`).
     * - `'shortDate'`: equivalent to `'M/d/yy'` (`6/15/15`).
     * - `'mediumDate'`: equivalent to `'MMM d, y'` (`Jun 15, 2015`).
     * - `'longDate'`: equivalent to `'MMMM d, y'` (`June 15, 2015`).
     * - `'fullDate'`: equivalent to `'EEEE, MMMM d, y'` (`Monday, June 15, 2015`).
     * - `'shortTime'`: equivalent to `'h:mm a'` (`9:03 AM`).
     * - `'mediumTime'`: equivalent to `'h:mm:ss a'` (`9:03:01 AM`).
     * - `'longTime'`: equivalent to `'h:mm:ss a z'` (`9:03:01 AM GMT+1`).
     * - `'fullTime'`: equivalent to `'h:mm:ss a zzzz'` (`9:03:01 AM GMT+01:00`).
     *
     * ### Custom format options
     *
     * You can construct a format string using symbols to specify the components
     * of a date-time value, as described in the following table.
     * Format details depend on the locale.
     * Fields marked with (*) are only available in the extra data set for the given locale.

     * Note that timezone correction is not applied to an ISO string that has no time component, such as "2016-09-19"
     *
     * ### Format examples
     *
     * These examples transform a date into various formats,
     * assuming that `dateObj` is a JavaScript `Date` object for
     * year: 2015, month: 6, day: 15, hour: 21, minute: 43, second: 11,
     * given in the local time for the `en-US` locale.
     *
     * ```
     * {{ dateObj | date }}               // output is 'Jun 15, 2015'
     * {{ dateObj | date:'medium' }}      // output is 'Jun 15, 2015, 9:43:11 PM'
     * {{ dateObj | date:'shortTime' }}   // output is '9:43 PM'
     * {{ dateObj | date:'mmss' }}        // output is '43:11'
     * ```
     *
     * ### Usage example
     *
     * The following component uses a date pipe to display the current date in different formats.
     *
     * ```
     * @Component({
     *  selector: 'date-pipe',
     *  template: `<div>
     *    <p>Today is {{today | date}}</p>
     *    <p>Or if you prefer, {{today | date:'fullDate'}}</p>
     *    <p>The time is {{today | date:'h:mm a z'}}</p>
     *  </div>`
     * })
     * // Get the current date and time as a date-time value.
     * export class DatePipeComponent {
     *   today: number = Date.now();
     * }
     * ```
     *
