/***********************************************************
This class will deal with all the aspects about animation related things.
To spawn a new animation state - reset it's state using state reset functions

Active - currently active animation state 
Default - when the active animation state expires it goes back to default state 

Normal - normal frame progression from 0 to maxFrameCount 
Reverse - reverse frame progression from maxFrameCount to 0 

doLoop - keep the animation in Loop 
isActive - only render if the state is active else it is ignored 
			default state is always isActive = true and doLoop = true
