Loader provides a mechanism to preload Cordova audio content via PreloadJS or internally. Instances are returned to
the preloader, and the load method is called when the asset needs to be requested.
Currently files are assumed to be local and no loading actually takes place.  This class exists to more easily support
the existing architecture.
