Rewrite schema generation (#1)

* Completeley rewritten schema generation
* Added support for python 2.7 and 3.4
* Restructured testing and build configuration
* Added nested request schemas

This rewrite completely replaces the public interface of the django rest schema generation library, so 
further changes will be needed to re-enable and further extend the customization points one might want.
