feldtruby 0.2.0

Robert Feldt's Common Ruby Code lib. I will gradually collect the many generally useful Ruby tidbits I have laying around and clean them up into here. Don't want to rewrite these things again and again... So far this collects a number of generally useful additions to the standard Ruby classes/libs and then includes a simple optimization framework (FeldtRuby::Optimize). email: robert.feldt ((a)) gmail.com
