Just some updates to the phpdocs as well as support for additional input formats for different functions

[chasepeeler]

0.) added .gitignore file 1.) Added @method documentation to the Client class for the method invoked via __call. geolocation is the only one I didn't add because something weird is going on there (the method in the Geolocation class is calling the requestHandler with too many parameters) 2.) Updated DistanceMatrix to support an array of origins or destinations, which will be imploded using the | 3.) Updated Elevations to allow specifying multiple locations based on the format of the input, which is documented 4.) Updated reverseGeocode to attempt to determine if a string value could be a lat,lon string, and if so, use it as such 5.) Updated timezone to accept more input types for the timestamp, including anything that can be parsed by \DateTime
