Index method on usercontroller returns all users.
Show action on UserController which returns a single user
Refactor the UserController tests to be in a better format
Create method on UserController creates the user and returns the id of the new user.  Planning on refactoring this into using an ActiveSerializer.  Also, private method on UserController to permit the params for creating the user...Rails 4 thing I guess
Add migration for putting back the counter cache columns.  Turns out I was actually doing a smart thing.  Remove some bad old migrations, and update the schema.rb
Change the cache counter names to the convention.  Enable cache counters for Image and Tag model relationship
add another cache counter to the user model, and update the migration again
Merge branch 'user_controller'
