This change adds or update a swath of tests to push method code coverage numbers up.
Yes, method coverage is not super meaningful, but it is one metric that we can use to
ensure at least minimal coverage of this library.
Almost no product changes in here.
This may be controversial but it we're doing it. Having code formatting needs to be consistent
and a non-issue during code review. I'm willing modify the configuration if people see a strong
need, but formatting needs to be present and enforced.
- Moved statistics methods from GHRepository to new class GHRepositoryStatistics
- Updated StatisticsTest to suit.
- For ContributorStats, put the "wait-till-ready" loop in the accessor method.
I'm planning to do something similar for the rest.
