Module vote 

Per-view vote collection and certificate formation.

Votes for views arrive concurrently, and each view is tallied on its own until it crosses a threshold and forms a certificate. VoteCollector owns the machinery common to every kind of vote, inspecting each vote only through the Ballot trait. It creates a task per view and voted epoch and routes votes to the appropriate task, drops duplicate and stale votes, buffers votes whose epoch is not yet resolved, and GCs decided views. How a task actually combines votes into an output is delegated to a pluggable Tally strategy.
