Enabled the Student School type updater.
The updater now passes along the runner URL to the starter function.
Also fixed the TaskRunner to display correct error messages when a invalid option has been specified.
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.
