<MSG> Decouple experiment starting from Split::Helper
Summary:
Allow RedisAdapter to be used outside of a session context
Remove unnecessary duplicate methods
Add debugger gem
Refactor finding experiments from Helper to ExperimentCatalog
Refactor experiment starting process from Helper to Trial
This refactoring further decouples the view helper from the inner
workings and detials of starting an experiment. This completes the
work needed to allow for an experiment to be started by an arbitrary
class.
This code is pretty rough and there is a lot of refactoring that
this gem needs to make me happy. But this gets that process started
and gets us the funtionality we need.
All but one spec are currently passing. It's a spec we don't really
care about for our own purposes, but I'll have it fixed before
doing a PR to the main split fork.
