[kepler-dev] subclassing actors: ptolemy.actor.lib.MonitorValue

[Matt Jones]

 Note also that there is an interaction with the Kepler GUI in terms of how
SVG icons are assigned using the icon assignment property files in the
configuration directory for Kepler.   We only allow the native ptolemy icon
to display in certain cases, which is configured in the icon mapping
property files.  See the comments in the top of those property files for
details.
