TKeyMapFile*

 Utility class for browsing TMapFile objects.

 When the browser is invoked for a TMapFile, a TKeyMapFile object
 is created for each object in the mapped file.
 When a TKeyMapFile object is clicked in the browser, a new copy
 of this object is copied into the local directory and the action
 corresponding to object->Browse is executed (typically Draw).
