	HOW TO Write a new Animation

A)	Think of a name, create a function Prototype right below this comment.
B)	Increment NUMOFANIMATION by the number of animations you are going to add.
C)	Put a function pointer to your new animation into the animations[] Array.
D)	Implement your animation!
	--> Get a buffer with buffNew(); Display it with setImage(); Free Buffer after usage!
