Example of an 2D "Open World" system using chunking

This system allows the development of a Scene that is comprised of multiple External Layouts, and the seamless traversal between those layouts. 

Requirements:

• Define a matrix of cells that lays out the orientation of each external layout in relation to each other. (See "Map" logic)
• Each external layout has a single ChunkZone object and all objects are inside of that zone
• Each ChunkZone must have an origin at (0,0) in the scene editor
• Every ChunkZone must be a square with the same width and height
• All objects in the zone must be added to the "ChunkedObjects" group

In this example, as the camera moves between zones the adjacent chunks are loaded, and remote chunks are culled.
