Major refactor of the access module The first step to sanity is a leap into the unknown? Create an object to represent the access checks for each module instead of a bunch of loose functions. Converted all views and params.py to use the new access checker. Main differences: * arguments to a checker can be passed by using a tuple * checkers are referenced by string, rather than directly * the Checker constructor handles merging with child views Patch by: Sverre Rabbelier

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.
