+/** This file contains ***INSTANCIATED DEFINITIONS*** of eoReal Init fns
+ * It should be included in the file that calls any of the corresponding fns
+ * Compiling this file allows one to generate part of the library (i.e. object
+ * files that you just need to link with your own main and fitness code).
+ *
+ * The corresponding ***INSTANCIATED DECLARATIONS*** are contained 
+ *       in src/es/make_real.h
+ * while the TEMPLATIZED code is define in make_genotype_real.h
+ *
+ * It is instanciated in src/es/make_genotype_real.cpp - 
+ * and incorporated in the ga/libga.a
+ *
+ * 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***
