SurLib with Test Geometry
===========================

The `--test` option results in a totally changed mesh0 
so actions done in GGeo::loadFromCache depending 
on specific geometry volume indices will go stale...

Idea for test geometry is to have all the materials
and just use simplified geometry. Problems are that 
surfaces via GSur wrappers mix properties with specific geometry:
 
* border surfaces need to use PV indices 
* skin surfaces need to use LV names

PMTInBox is the test geometry that most needs 
to have proper surface handling... 
Hmm getting the general case to work just for the cathode
surface seems overkill..

So stick with CTestDetector::kludgePhotoCathode for now.
