Use manager.dict from multiprocessing to store genome

[gnypit]

In order to ensure proper handling of different data types of genes in the parallel GA they should be stored inside a dict using the Manager class from multiprocessing. Chromosome class should take a list of genes and an instance of the Manager class as input in the constructor. Next, in the field genome a manager.dict with genes as values should be remembered to allow child processes using them for fitness evaluation.
