This function deletes an existing item from a vector model, releasing the memory referenced by the
item pointer and removing that pointer from the model's array of item pointers.
[in] Pointer to the IVectorModel interface object.
[in] Indicates the zero-based index of the item to be removed from the vector model. The first
item in the model is indexed by 0, the second is indexed by 1, and so on. So, if
IVectorModel_DeleteAt is called with nIndex equal to 2, item 2 will be removed from the
vector model, with items 3, 4, 5, etc all shifting one position lower.
