Detailed Description

Space is a group of owned geoms, and a level of collision.

Space is actually a special geom that contains other geoms and that has no position nor orientation, used for collisions (spaces themselves are tested before the contained geoms). It is used to make collision detection go faster by grouping geoms. You should encapsulate only pertinent groups, or performance would suffer of a bad architecture. Note that it owns the contained geoms.
