This is required if you want to use the method getParamWithLongName that allows
one to get a value of a parameter read somewhere else.
After changing 3 calls due to that, I decided to change ALL calls within
the make_xxx functions
that makes full use of libes.a.
The user guide is in Lesson4 of the tutorial - programmer's guide
will come later.
Plus many small changes here and there
src/es/eoEsGlobalXover.h and src/es/eoEsLocalXover.h for crossover
src/es/make_XXX_es.h for user-input
test/t-eoEsAll.cpp to test
However, an old bug appeared: className was not const in eoGenOp (and derived classes)
so I had to change that throughtout the hierarchy
