Detailed Description

The btTriangleIndexVertexArray allows to access multiple triangle meshes, by indexing into existing triangle/index arrays.

Additional meshes can be added using addIndexedMesh No duplcate is made of the vertex/index data, it only indexes into external vertex/index arrays. So keep those arrays around during the lifetime of this btTriangleIndexVertexArray.
