Hello,
I updated the CbmEmc.cxx file.
Now the materials are loaded from the media_pnd.geo file, while before they were hardcoded.

This changes even some media parameters of the early version, which was almost taken from the CBM ecal. In particular for PWO.

material__OLD_____NEW
epsil______0.1____0.001
madfld___100.0___AUTO
maxstep___0.1____AUTO
maxde_____0.1___AUTO
minstep____0.1____AUTO


where:
float epsil - boundary crossing precision EPSIL
float madfld - maximum angular deviation TMAXFD due to field
float maxstep - maximum step permitted STEMAX
float maxde - maximum fractional energy loss DEEMAX
float minstep - minimum value for step STMIN


It should not affect too much the analysis. In each case the "AUTO" values are automatically calculated by geant, so they can be trusted more than with the old setup.
