0002 CSGOptiXSimulateTest
0003 ======================
0004
0005 Canonically used by cxsimulate.sh combining CFBASE_LOCAL simple test geometry (eg GeoChain)
0006 with standard CFBASE basis CSGFoundry/SSim input arrays.
0007
0008 Notice that the standard SSim input arrays are loaded without the corresponding standard geometry
0009 using the intentional arms length (SSim subdirectory/NPFold) relationship between CSGFoundry and SSim.
