fix swagger examples
Added a restful.Route pointer to restful.Request wrapper so that route information is available in the filters and handlers.
Implements #100
Changed the implementation to address code review feedback
	- Exposing only the path in request, not the whole route object
	- path is private, read only, available through SelectedRoutePath() method
	- added a UT to test the functionality

implements #100
