Added requisite classes for retrieving users
I added a Get controller and a Request Observer for the User class, along with the model needed for using them (as no User model existed yet).  I also added a method to User that converts a JSON string to an array of Users.  The next step is to write tests for these controllers, model, and the addition to User.java.
