* Removing viz dependencys from derivparam
** Move LevelUtilities to common
** Use spring instead of eclipse plugin extentions
to configure derived parameter function types
** Use RequestRouter instead of ThriftClient so
we can use IServerRequest objects in both CAVE
and EDEX
The next stage will be to clean up exceptions in
derived parameters to stop using VizException and
VizCommunicationException.
