//
// .NAME:
//  MacroVisitor
//
// .AUTHOR:
//  Gilberto Camara and Fernando Ii
//
// .SUMMARY:
//  Defines a class for generating macro programs
//  from a display window.
//
// .CLIENTS:
//  SuperPage, Page
//
//
// .RESPONSABILITIES:
//  - For the caller (superpage or page), save its name and
//    requests which was used to create it.
//  - For the caller and all its children, save the drop
//    actions associated with data units and visual definitions
//
// .COLLABORATORS:
//  MvIconDataBase (stores the relations between presentables,
//  data units and visdefs)
//
// .BASE CLASS:
//  Device
//
// .DERIVED CLASSES:
//  (none)
//
// .REFERENCES:
//   The implementation of this class is based on the "visitor"
//   pattern (See "Design Patterns" book, page 331).
