Changed the one line in EntityFramework\BitVector.cs.
"Completed" the initial version of the animation system. It allows you to switch the animation of the sprite by changing the currentAnimation string.
The animation systems allows as many animations as you can fit on a single spritesheet.
The way animations are defined is by using an XML file to with the same format as the one in the Content folder. Template coming to the wiki.
Still need to figure out a way to put currentAnimation into the animation component instead of the spritesheet object.
