• Population.rng has been promoted to Population.RNG. This makes it easier to implement custom models in another package than gago
• Renamed Enhance to Evolve for esthetics
• Refactored parallel code for reusability

The Genome's Crossover method now has to be done in-place. Although this breaks the API it is well worth as it makes it more consistent and requires less boilerplate code for deep copying.

Fixed a bug where the individuals were evaluated twice when ParallelEval was true.

The best individuals are now stored in the HallOfFame field. This is a breaking change because the Best field does not exists anymore.

Individuals can now be evaluated in parallel thanks to the GA's ParallelEval field.

The GA struct now has an RNG field of type *rand.Rand which can be set to make results reproducible.

Remove data race in GA.Initialize

• Added GA.Initialized() to indicate if a GA has been initialized or not.
• Back to 100% test coverage
• Tidied naming
• Added String() functions to Individual and Individuals
• Added sub-tests to table-driven tests

Latest stable release for godep. Ensuing updates will be available through releases (aka the proper way).
