It is no longer derived from eoPop, it now gets a destination population.
This saves a lot of copying. The semantics has changed a little as well. It is
now an _infinite_ iterator. operator++ will *not* dispense new individuals, but
will merely stay at the end. To get a new indy, use operator*() as before.
eoEasyEA now checks the checkpoint *after* making a generation and clears the offspring
eoGeneralBreeder is changed to reflect the changes in eoPopulator
eoSequentialSelect now uses setup() rather than init()
I also changed
- the eoQuadratic into eoQuad (as dicussed with Maarten)
- the eoBin into eoBit, with more appropriate names for the "binary"
operators (that can be unary!) as no one protested when I posted on
eodev list
