I have separated the include files into

Browse source 
eo   everything that is general to any representation
   es.h everything about real representation (in es dir)
   ga.h everything related to bitstring representation (in ga dir)

To be continued by gp.h, and ...

This has lead to some slight modifications in test file eobin and all tutorial
examples files...
