Common Codec.map functions

[jenetics]

Jenetics requires the Chromosomes in a Genotype to have the same Gene type. Sometimes it is necessary to have chromosome with different gene types, which is not possible. One solution for this problem is to use one Gene type, e.g. DoubleGene and do the mapping in the Codec.

final Codec<int[|, DoubleGene> codec = Codecs.ofVector(DoubleRange.of(0, 1), 10)
    .map(v -> DoubleStream.of(v).mapToInt(d -> (int)d).toArray());

This ticket is about to add some commonly useable mapping functions.
