[sikora507]

I've added new chromosome capable of storing values between min and max value for any given number of bits.
For example
If we want to store values between -5 and 5 in 3 bits, we have 2^3 = 8 values available.
That way [0, 0, 0] will be minimum value (-5) and [1, 1, 1] maximum value(5).
[0, 0, 1] will become -3,75
[0, 1, 0] will become -2,5 and so on, up to [1, 1, 1] = 5

Improve code coverage

Please, add tests to validate the below ScalableFloatingPointChromosome's methods:

• CreateNew
• ToString

You can look into FloatingPointChromosomeTest for some test samples.

It would be nice too if you add a test to the GeneticAlgorithmTest, like Start_FloatingPoingChromosome_Evolved to assert how ScalableFloatingPointChromosome performs with the whole genetic algorithm and some genetic operators.
