Removed todo that has been added to trello
Extracted out an interface for field generator handlers and made all the handlers public so they can be reused or extended by users of the library
Also moved the static numeric types array from the generic class to a non-generic class to save on unnecessary memory use
Fixed some minor xmldoc warnings
Made the methods in FieldGeneratorHandler static
Changed the FieldGeneratorHandlersRouter to only return the correct handler and thus removed the need for having the field configuration as an instance variable in fg handlers
Ensured the field generator handler is passed into the template method to modify the config
Added some conditional logic to apply the form-control class in the Twitter Bootstrap template - still need to look at bools and select's
