coco 0.4.2

"Another code coverage tool for ruby 1.9 (from the famous post of Aaron Patterson). This one suits my needs: * Use it from rspec with a simple <code>require 'coco'</code> * Display filenames covered < 90% on console * Build simple html report only for files covered < 90% * Report sources that have no tests * UTF-8 compliant * Configuration could be done via a simple yaml file * Colorized console output (*nix only)
