in some files (and some bugs were fixed as well [Marc: eoOneToOneBreeder was a mess])
eoFunctor.h now contains static functor_category members, this shouldn't hurt anyone.
Apart from big changes in the src/ga dir, and the addition of the src/do dir
it also generated a few changes here and there, e.g. some include file still
missing. Also removed some warning from some test files.
2 new important classes: eoPerf2Worth and eoSelectFromWorth
Instances of eoPerf2Worth are eoRanking and eoLinearFitScaling.
Coming soon (piece of cake now) are the niching strategies (sharing, clearing)
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: ???
