Here's my solution to HipChat test assesment.

To install requirements run

$ pip install -r requirements.txt

To test the solution in terminal mode just run

$ ./parser.py

And follow on screen instructions.

NOTE 1: parse() result converted to JSON only at the printing stage while it was required to return JSON. It just seems to be a bit more intuitive for me. Anyways, I hope it's really minor issue.

To run tests simply run

$ nosetests
