* Refactoring poll/vote/skip logic Favor asking the poll if the user has already voted instead of relying on the poll vote or skip to know about the implementation details (e.g. should a poll vote know that there's a related model call poll skipped? likely not) This refactor also tidies up the specs, for which there's quite a bit of chatter. Found via the `flay` gem. * Adding method documentation Also need to bump gitpod's build as it halted for the prior commit.
