README
Fix typo.
Spacing of bullets.
Write MemoizedObjective decorator.
Add a minor type bound.
Alter SimpleCircleOfLife to take multiple PopulationMetrics.
Add null check in equals methods.
Rename PrintingPopulationMetric to PrintAllPopulation metric, and have it take a Writer instead of being hard-coded to use standard out.  Accordingly, IOExceptions may now be thrown by the evolutionary loop.
Fix wrong class name in exception.
Separate PrintAllPopulationMetric into PrintIndividualsPopulationMetric and WriterPopulationMetric, which decorates metrics with a Writer.  Add a flush() method to the PopulationMetric interface, and call it at the end of SimpleCircleOfLife.evolve().
Implement mean, std, max and min functions for measuring the fitness of populations.
Metrics now print out the number representing the generation the sample was taken from.
