/*
 * This fuction does the create an eoInit<eoOneMax>
 *
 * It could be here tempatized only on the fitness, as it can be used 
 * to evolve structures with any fitness.
 * However, for consistency reasons, it was finally chosen, as in 
 * the rest of EO, to templatize by the full EOT, as this eventually 
 * allows to choose the type of genotype at run time (see in es dir)
 *
 * It returns an eoInit<EOT> that can later be used to initialize 
 * the population (see make_pop.h).
 *
 * It uses a parser (to get user parameters) and a state (to store the memory)
 * the last argument is to disambiguate the call upon different instanciations.
 *
 * WARNING: that last argument will generally be the result of calling 
 *          the default ctor of EOT, resulting in most cases in an EOT 
 *          that is ***not properly initialized***
