type VoteSet 

type VoteSet struct {
	// contains filtered or unexported fields
}

VoteSet helps collect signatures from validators at each height+round for a predefined vote type.

We need VoteSet to be able to keep track of conflicting votes when validators double-sign. Yet, we can't keep track of *all* the votes seen, as that could be a DoS attack vector.

There are two storage areas for votes. 1. voteSet.votes 2. voteSet.votesByBlock

`.votes` is the "canonical" list of votes. It always has at least one vote, if a vote from a validator had been seen at all. Usually it keeps track of the first vote seen, but when a 2/3 majority is found, votes for that get priority and are copied over from `.votesByBlock`.

`.votesByBlock` keeps track of a list of votes for a particular block. There are two ways a &blockVotes{} gets created in `.votesByBlock`. 1. the first vote seen by a validator was for the particular block. 2. a peer claims to have seen 2/3 majority for the particular block.

Since the first vote from a validator will always get added in `.votesByBlock` , all votes in `.votes` will have a corresponding entry in `.votesByBlock`.

When a &blockVotes{} in `.votesByBlock` reaches a 2/3 majority quorum, its votes are copied into `.votes`.

All this is memory bounded because conflicting votes only get added if a peer told us to track that block, each peer only gets to tell us 1 such block, and, there's only a limited number of peers.

NOTE: Assumes that the sum total of voting power does not exceed MaxUInt64.
