We have no idea if a population can be some other thing that a std::vector, but if somebody thinks of it, this concrete implementation can be moved to "generic" and an abstract Population interface be provided.
The template can be instantiated with anything that accepts a "size" and eoInit derived object. in the ctor. EOT must also have a copy ctor, since temporaries are created and then passed to the eoInit object
