Create MovingQuad.java

This program was made after typing up two tutorials about LWJGL. I combined drawing a quad and  input handling in this one. You can move the quad around using the WSAD keys, and Q exits the thing. The Multidimensional point array can be confusing. 

This may help, X0 and Y0 are on the bottom left of the display, and the quad is drawn from bottom left to bottom right to top right to top left, counter clockwise and such is the order of coordinates in the multidimensional array.
