    Author:     Tim_Browse (Xara Group Ltd) <camelotdev@xara.com>
    Created:    6/7/93
    Inputs:     ModuleID - the ID of the module that owns this Tool.
    Outputs:    -
    Returns:    -
    Purpose:    Create an OILTool object that can be linked to a Tool object (via a
                ToolListItem object).  This object (the OILTool) knows the instance handle
                of the DLL that contains the tool.
