Add new dependances for cake layer Evolution

[reyman]

Actually Evolution component is defined like this

trait Evolution extends Termination
    with Lambda
    with G
    with F
    with P
    with Archive
    with Breeding
    with Elitism { self =>

It seems an evolution metaheuristic also need :

• a mapping function between Genotype and Phenotype, it can be used to define different sort of problem resolution : genome -> simulation, genome -> mathematical function
• objective functions, the actual evaluation() function defined in Problem Class

A proposition ?

trait Evolution extends Termination
    with Lambda
    with G
    with F
    with P
    with Archive
    with Breeding
    with Elitism 
    with GtoPmapping
    with ObjectiveFunctions { self =>

Complete re-factoring make that request obsolete.
