/*!
In most cases, a reproducer generates new organisms using parents
selected (by fitness) from an existing population. In some singular
(and probably rare) cases, a reproducer might generate new, random
organisms in order to keep diversity high.
Reproduction techniques can include crossover and asexual, sexual
and (my favorite) try-sexual models.

A virtual destructor. By default, it does nothing; this is
