BurnDepositNoThreshold has a default value of 0.8.

Just one change I would suggest doing, but aside from that it looks good

let's hold off from merging for now, but LGTM

Good catch, I converted all to MustNew* and so removed the returned error from getQuorumAndThreshold and from Tally function. 658af5d
