MTLMesh is the geometry i.e. vertex buffer, index buffer required to render a 3D Shape. So, if we create say 10 Spheres as `Sphere(50)`, then it creates 10 MTLMeshView and only 1 MTLMesh shared among MTLMeshView.

The mesh is used on native side, Please check MetalMesh.render() method in the PR. 
This aligns very much with D3DMesh, ES2Mesh.
