+ Renamed HomeController to FactoryController
+ Added an attributes_for action which is analogous to FactoryGirl.attributes_for
+ Improved error handling, FactoryController#create and FactoryController#attributes_for both return 422 with errors json when given an undefined factory or upon validation error
Refactoring a few methods to slim down some methods
