Class: AABB
AABB is an Axis-Aligned Bounding-Box, this is a rectangle that has no rotation; it is aligned with the X and Y axis. The AABB is defined by a centre and width and height dimensions, it can be used for faster collision detection as it is a more simple shape, requiring less calculations than a fully defined polygon.
