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
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
Changed es.h in src/es into make_es.h (was ambiguous with src/es.h)
Changed the interface of make_genotype - now templatized by the EOT
and not the fitness - this is mandatory for ES genoptypes as it allows to
choose the type of gentype at run-time (from existing types, of course!)
Also moved make_help.cpp into utils dir (otherwise you'd had to maintain
a copy into each representation dir!).
