cool I will check... Is there a standard for metric_fu to receive errors yet?

Like if churn can't churn a project because there is no supported SCM found, or just because of some parsing error... can I return back `{:error => 'Churn Failure: No SCM for project found.'}`. Does working on something like that make sense or should we expected the actual exception to raise up and the emit function to capture and rescue errors... Such as `rescue Churn::NoSCM` and other expected failures?
