    00006 /*
    00007 Template for creating a new representation in EO
    00008 ================================================
    00009
    00010 This is the template main file.
    00011 It includes all other files that have been generated by the script create.sh
    00012 so it is the only file to compile.
    00013
    00014 In case you want to build up a separate library for your new Evolving Object,
    00015 you'll need some work - follow what's done in the src/ga dir, used in the
    00016 main file BitEA in tutorial/Lesson4 dir.
    00017 Or you can wait until we do it :-)
