1/ Changes in SimpleUniverse classes ported back to Sophya/LUC and a new class
InterpCosmoCalc (Interpolated cosmological calculations) added to Sophya/LUC
and used in classes in gftdist.h .cc
  2/ Optimized computation of integral of LF (classes like CumulDistM DrawZ) -
time needed to run baseSimulation decreased to ~ 15 minutes instead of hours
more work needed to clean and optimize Schechter & LF classes
  3/ Separated SED/Filter classes from the one related to PCA analysis
  (two new files sedpca.h .cc added and makefile updated)
  4/ Minor corrections done in few main programs to ensure proper compilation
  5/ Some changes done to mass2gal.cc ( class Mass2Gal ) and progs/rdlss.cc
to ensure correcting reading of LF (using the LFParameters class) and added
also some progress indicator when creating catalog
