Suppress Coverage.py warnings
First of all, thanks for the excellent plugin. The coverage plugin that comes with nose does a terrible job of handling subprocesses, so your plugin is much appreciated.
Anyway, I do seem to be inundated with "Coverage.py warning: No data was collected." messages whenever I use your plugin, even though it pulls out the coverage information just fine. I'd really appreciate it if there was someway to filter out that message. As it stands, it's very difficult to follow what's going on with my unit tests when I have that message repeated hundreds of times.
