Title: Stops Buffer Coverage tests

This adds a test for the stops buffer coverage ratio indicator, as well as a type framework for providing params to indicators within tests.

@lossyrob, I suspect that the stuff I'm doing with nested traits could potentially be better handled by implicit type conversions but I wasn't sure so I went with this in the interest of time; I'm happy to refactor if there's a better way.
