// Desc: Implements the ID3DXAllocateHierarchy interface.
// In order to create and destroy an animation hierarchy using the 
// D3DXLoadMeshHierarchyFromX and D3DXFrameDestroy functions, we must 
// implement the ID3DXAllocateHierarchy interface.  In doing so we define how
// meshes and frames are created and destroyed, thereby giving us some 
// flexibility in the construction and destruction process.
