test(Tests.cpp): Tiny experiment to increment maxIterations

Now the maxIterations for each Game are incremented and it is
also checked if the right amount of iterations have been performed
when carrying out the Game.
feat(ValueFunction): Add Getter for amount of performed Iterations

Now it can be retrieved how many iterations where performed in the
computation of a instance of the ValueFunction.
feat(Game): First Version of the Game solver

It does not pass all the tests yet but a lot of it is already
working, including the TinyTest examples.
