Part-way through support for pytest
Implemented a very basic wrapper using pytest to collect available tests
Test discovery now using dot-separated-line namespace thing
Basic test discovery for unittest2-style test collections added
Functional test execution.

Discovered names are still not properly matching the execution namespace, but this is well on the way now.
Functionally accurate with respect to discovered names and executed names.

Appears to be an issue with always running all of the tests?
Just the sugar
Now supports proper re-running of individual tests
Removed dependency on pytest.
Complete rename from pytest to unittest
Minor namespace refactor
Update docs for unittest usage
Merge branch 'master' into merge
Merge pull request #13 from tleeuwenburg/merge
