Adding solution for n queens problem using GENETIC Algorithm

[Radwojt]

Affect: #132

I have implemented genetic algorithm for solving N-Queens Problem.
This is heuristic problem so remember that given input data generates randomly.

The problem is solved when each queen cannot perform attack to each other.

I will be happy to answer any questions :)
