-     OVERVIEW

-     ========

-     Base class (interface) for command pattern.  A

-     command encapsulates a single editing operation

-     that may be performed on a document.  Each command

-     may be done or undone multiple times.  The specialized

-     implementations for each type of operation are re-

-     sponsible for providing a means to return the model

-     to the prior state.
