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.
