Yesterday I finished implementing all the features that I had planned (and more).
Some of those features:
* New CodeRank metric where the use of a system call is weight by that function's code rank.
* Provide a non-graphics interface to using tool.
* Provide the ability to write custom plugins for collecting data and creating reports from unit test data and example application repository.
* Enhanced the grid view to visualize coverage information.
I also have a couple more ideas for plugins and how to use the data, but first I want to check in my code and make sure there is sufficient documentation.
