test-unit-context 0.1.0

Makes Test::Unit::TestCases 'contextable' and thus much easier to read and write. If you've seen RSpec than it's the very same 'context do ... end' re-invendet for Test::Unit. Inspired by gem 'context' that does the same for the 'old' Test::Unit 1.2.3 bundled with Ruby 1.8.x standard libraries.
