namebox 0.2.2

Create namespace boxes to protect the core classes' methods from changes, like refinements. This version is only compatible with Ruby 1.9.2 or greater. For use with Ruby 1.8.7 or 1.9.1, get the version 0.1.8 or 0.1.9. Note: this version is under tests, and can be considered a pre-release for 1.0.0. Please, came back soon to check for that version. ;-)
