Trait decoded implemented

Genome can be queried by calling function GetTrait(chromosome number,
trait).
Function returns single int
- plain number in case of NUMBER trait
- red << 16 | green << 8 | blue in case of COLOUR
- index into MyDictionary.EnumShape array of string in case of SHAPE
trait. Just call GetShape(index) and String representation of correct
shape is returned.
- index into appropriate Enum in case of All other traits

Note that I have generated 20 random genomes in
eap_frontend\Assets\Scripts\Backend\OutputOfTests\Complete_Genomes. They
also contain the phenotypes, i.e. decoded traits. I think we should
manually check them to determine, whether there isn't some bug in
decoding traits.
