while creating an instance, use class aliases for restler formats, filters and apis
avoiding unneeded dot in error message
refactored setProperties method as initialize and take class name or an instance as the first parameter
modified restler to use initialize when ever possible for object instantiation and property setting
previous update makes it possible to use restler with composer's autoloader
Rearranged the method order and changed addPath to be a protected function
import and export previously created routes from Routes class for caching purpose and added comments to explain public methods
removed temp cache (used for testing)
restler to use new router to replace its internal routing methods :)
