* 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***
