[kepler-dev] Events in Ptolemy?

[Christopher Brooks]

Hi Ben,
Sorry for the delay.
The primary run time event system is mostly in Manager, which has
an inner class called State.  We use these States to update the
status bar.

Let me know if the States in Manager are not sufficient and you'd
like some additional states.
