Added the Model project and the ModelTest project.

The Model project is where all of the logic code is going to reside.

The ModelTest project is where all of the testing code is going to reside.

I've also added a Card class. This just holds the information of a card.
Chavas makes people lazy.
Added the Hand class.

Also changed around the test code for Card.
There obviously needs to be a file for the Hand class.
Movement validation added.
