To be able to use the primitive std::generate function, added a
set of wrappers in eoSTLFunctor.h that have the copy semantics most
STL functions expect (namely pass-by-value rather then pass-by-reference).
Updated test/Makefile.am to also test t-eoRandom
Changed the signature of eoMon, eoBin and eoQuadOp to return a bool,
without invalidating fitness. Added a set of invalidators to take over
that job (see for instance eoSGA and eoSGATransform how this can transparantly used)
Derived eoState from eoFunctorStore (for convenience, from a design perspective this may sound wrong)
Added a wrap_op function that does the wrapping for you (see eoOpContainer how this made this functor
exceedingly less hairy). Checked all the tests removed the eoGeneric*Op family (not needed anymore)
and of course changed all the operators to reflect the change (and found a few that didn't
invalidate the fitness, thus really pointing out the advantage of the current approach)
Pop: error in nth_element_fitness
sga: error in eval
eoParseTree: oddities with gcc
checkpointing: added eoParser and eoState
eoParser: support for wrongly entered parameter names
rnd_generators: flip(0.5) -> flip(bias) in binary_generator
selectors.h: ???
