Detailed Description

This class manages a sub part of a mesh supplied by the btStridingMeshInterface interface.

Simply create this shape by passing the btStridingMeshInterface to the constructor btGImpactMeshShapePart, then you must call updateBound() after creating the mesh
When making operations with this shape, you must call lock before accessing to the trimesh primitives, and then call unlock
You can handle deformable meshes with this shape, by calling postUpdate() every time when changing the mesh vertices.
