Optimize Convex Collision

Browse Source 
Implements the Gauss Mapping optimization to SAT convex collision test.

* Described [here](https://ubm-twvideo01.s3.amazonaws.com/o1/vault/gdc2013/slides/822403Gregorius_Dirk_TheSeparatingAxisTest.pdf) by Dirk Gregorius.
* Requires adding of face information to edges in MeshData
* Took the chance to convert MeshData to LocalVector for performance.
