2#  COMPONENT: analyzer - output area for Rappture
3#
4#  This widget acts as the output side of a Rappture application.
5#  When the input has changed, it displays a Simulate button that
6#  launches the simulation.  When a simulation is running, this
7#  area shows status.  When it is finished, the results appear
8#  in place of the button, according to the specs in the <analyze>
9#  XML data.
