AllocateHierarchy.h：源码内容
							//--------------------------------------------------------------------------------------
// 头文件: AllocateHierarchy.h ， 作者：曾凡喜

// 该头文件实现了D3DXFRAME_DERIVED结构体，D3DXMESHCONTAINER_DERIVED结构体，CAllocateHierarchy类
//
// 分别派生自D3DXFRAME结构体，D3DXMESHCONTAINER结构体，ID3DXAllocateHierarchy虚基类
