Removed unnecessary properties from attachment model. Exposed GMT times on post and page.
Added term model.
Different models (image, video, file) will be instantiated depending on what kind of attachment we're dealing with. Video object needs to be defined.
Added method addData() for end user mappers to add data to individual results instead of having to share the one used by WPMVC and needing to call parent::addData().
Added method addToPayload() for end user mappers to add data to the entire payload instead of having to share the one used by WPMVC and needing to call parent::addToPayload().
Modified ClassFinder to default to post controller, mapper, and model if  the searched for one isn't found. This makes sure that if a user is is trying to find a custom post type, they do not HAVE to create a mapper and model for that type in their app.
Removed collection name. ClassFinder now accepts group and object as its params. Knowing the full name of the class is no longer necessary.
Added some comments.
Add 'term_' to stripped prefixes. Removed some items from the fieldmap that were unnecessary.
Made some methods protected instead of public.
Added featured image back to Post mapper, but checked to see if post thumbnails are supported by the theme first.
Fixed a couple bugs -- one passed by reference error and the other just a typo.
Retrieved default posts per page from WP.
Added some site date to payloads.
