Simple function for chaining an array of promise functions. Every function in the
promise chain needs to be uniform and accept the same input parameter. This
is used for a number of things, but most importantly for the service call chain
by API.

@param calls Functions that should all take in a value and return a promise or another object
@param val The initial value to be passed into the promise chain
