    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.
