Changes to genome part of backend

Methods bodies haven't been implemented yet, but stubs with comments are
defined.
MyDictionary added and Gene class changed

I have started to implement MyDictionary, where I created several static
arrays (some of them multidimensional) for convenient reference to names
of genes, coded names of genes, names of chromosome etc. Constructor of
gene giving random gene also implemented (taking on which chromosome it
is and which gene on it it is).
Merge conflicts resolved

Minor conflicts resolved manually (only noticeable conflicts in the Gene
class).
