Make the timeline View work directly on the GSoC timeline for the time being.
This will help us get rid of the weird TIMELINE_LOGIC constant we are using now to switch between the different timelines. The other timelines should get their own View module.
Coverage: code coverage testing for Python
Coverage.py is a Python module that measures code coverage during test execution.
It uses the code analysis tools and tracing hooks provided in the Python standard
library to determine which lines are executable, and which have been executed.
