oktest 1.2.1

Oktest.rb is a new-style testing library for Ruby. * `ok {actual} == expected` style assertion. * **Fixture injection** inspired by dependency injection. * Structured test specifications like RSpec. * Filtering testcases by pattern or tags. * Blue/red color instead of green/red for accesability. * Small code size (about 2300 lines) and good performance.
