* - pass the Chromosome(s) to JEvolution
* - pass your Phenotype class to JEvolution (see ParaboloidPhenotype.java)
* - run it
*
* These necessary steps are indicated by `+` in the comments,
* the `-' lines are optional (the 'o' lines depend on the nature of the problem).
* Note that all parameters have default values
