          IndexBuffer manager will be the same as VertexBuffer manager, however, its for IndexBuffers.

Alright its time to get started one then I can add in the rest of reloadInit + reloadRelease

Alright here is the interface for this new render addition to the render system.

    void add(std::string name);
    void release();

    void reloadInit();
    void reloadRelease();

    void add1(std::string name, int x);
    void add2(std::string name, int x, int y);
    void add3(std::string name, int x, int y, int z);
    void add4(std::string name, int x, int y, int z, int w);
    void clear(std::string name);

    void bind(std::string name);
    void unbind(std::string name);

    void update(std::string name);

The nice thing about the index buffer interface is that similar to the vertex buffer.
