Small documentation changes, and also implemented the "GetCreator()" method from the WorldProxy class.
Minor doc fix, and serialization method rename.
Moved the MathTool class functionality to the "MathTools" namespace.
Added an AABB class that will be used by the proxy classes, and is just generally useful for query.
Modified constructors for soft and ghost proxies due to the constructor change in their base class.
Created a new sphere primitive class for math query operations.
Compile fixes for the sphere class.
Cleaned up the Plane class a bit in preparation for adding some functionality to it.
Renamed a few methods, and added a radius constructor.
Added serialization logic for the Sphere class.  This should make the Sphere complete.
Added methods to detect overlap with other math geometry to the plane class.  Not yet implemented.
Added a series of methods to the MathTools namespace that will aid in queries with geometry classes.
Added a copy constructor, made the data members public, and a few other minor touchups to the AABB class.  Still WIP.
This should mark the 95% complete mark for the Rigid Proxy class.  Only minor methods still need to be wrapped, if any.
Added a method to get the physics proxies AABB.
