create a testsuite

[evertlammerts]

I'm making a start with white- and blackbox testing. I will start with writing unit tests for SemanticizerFlaskServer which is the entry point of the application. This can then be used to create a text fixture for black box testing of the API.

For now I'm using stdlib's unittest and mock.

I will have to refactor the existing code to make it suitable for unit testing. I've created a separate branch for this (evert). I'll document all changes in tickets. When everybody agrees on the changes we can merge the branch back into master.

Plan sounds good. I see a lot of people using nose, might also be worth a look. Some of the files contain some simple testing examples, such as processors/semanticize.py and processors/feature.py.

With commit b5ca7d6 we're getting close to small units of testable code. Broke logging in the process though, still a short way to go.

Nose is much easier. It doesn't require all these useless testcase classes: just define a bunch of functions called test_*.
