CGXExcelChildFrame provides the implementation for a frame that contains a workbook grid that can read and write Excel files. The functionality of this frame is two pronged. It derives from CGXWChildFrame and contains all the associated code that comes with this frame class to deal with workbooks. For more information on this please refer the Objective Grid documenation on CGXWChildFrame. Another aspect of this frame implementation is that this this frame will call the special intialization functions at the correct time. The one step intialization of view with OnInitialUpdate that is the default with MFC framework application is not sufficient for our purposes. We do a two phase read:- one to get the actual tab count and two to get the actual data.
