Initialize a new EventsIterator. Iterate over all events in a trail..
@param {TrailDB} tdb - TrailDB object.
@param {Boolean,Object}
options.toMap - Whether the iterator should return a map for each event,
grabbing the appropriate key names. Defaults to a list with
just values.
options.filter - T_TDB_FILTER event filter struct (optional)
@return {EventsIterator} iterator.
