  This class implements a GUI application for exporting data to
  another level in the IDL call stack.

Calling Sequence


  mgh_new, 'MGH_GUI_Export', values, captions

Positional Parameters

    An array of pointers, each holding a data item that the user may
    want to export. The object destroys all pointers when it is
