Added CGPointGetOriginByCenteringRectOfSize to CLGeometry for returning the origin that will put the rect of size in the center of its parent frame.
Created CLGeometry for providing useful geometry based methods. Mostly C methods at the moment as these make more sense and are consistent with CoreGraphics styl CGRectMake.. etc...
Created CLKit which imports all the high level classes.
Created CLFoundation which imports all the low level classes.
Updated test project with new imports.
