Added conversion methods for Ogre::Sphere to Mezzanine::Sphere.
Added a Ogre::Sphere assignment operator and constructor to Mezzanine::Sphere.  Also made some compile fixes.
Added some extra utility methods to the Plane class, as well as serialization methods.  The touch-ups to the Plane class should now be more or less complete.
Minor simplification of code in Mezzanine::Plane.
Minor documentation fixes.
Warning fix.
Implemented more MathTools methods.  Only ray intersection methods remain.
More compile fixes for plane deserialization.
Added minor utilty functions that will set values based on highest and lowest values between two vectors.
Added a large quantity of new methods to the AABB class.  This should make it more or less complete for now.
Added missing constructors/destructors.
Minor fixes and clarifications regarding ray cast results.
Completed the Ray revamp.
Updated the RayQueryTool to access the renamed members of the Ray class.
Finished implementing geometry intersection code in the Mathtools.
