Add an argument specifying tournament (pool) size in the tournament selection operator

[gnypit]

In genal/selection_operators.py tournament selection operator by default treats the number of mating parents as the tournament (pool) size. There should be an argument specifying the pool size, which is:

• an integer such that 0 < pool size <= number of parents mating;
• stored within the Generation class;
• passd on to each Generation class' instance within the Genetic Algorithm.

Probably firstly the relationship between Generation and GeneticAlgorithm classes should be cleaned up and reorganised. However, solving this example might be a good example on how to handle args for different operators between various generations in the genetic algorithm.

@gnypit, what's up?
Should I try to resolve this issue?

Hi @alguiguilo098 ! That would be great 😄

@gnypit what, up ?

you want Generation class stored pool size, send argument in constructor ?

Hi! I saw you added it as a field in Generation class, that's great ;) thanks for the help!
