// the interface for your collection class in an IDL file.  Here's the example for the
// above declaration:
//
// interface ISomeCollection : IDispatch
// {
//      [propget, id(1)] HRESULT Count([out, retval] long *pVal);
//      [id(2)] HRESULT Add([in] ISPCChart* inItem);
//      [id(3)] HRESULT Remove([in] long inIndex);
//      [propget, id(DISPID_VALUE)] HRESULT Item([in] long inIndex,
//                                               [out, retval] ISPCChart** outChart);
//      [propget, id(DISPID_NEWENUM)] HRESULT _NewEnum([out, retval]LPUNKNOWN *pVal);
