A Gno port of the classic Solidity "Ballot" voting contract: a chairperson seeds a fixed list of proposals and grants specific addresses the right to vote, and each voter either casts a direct vote or delegates their weight down a delegation chain (with a loop guard, just like the original). WinningProposal/WinnerName report the current leader live, so there's no separate close-the-vote step. It's neat because delegation composability - a delegate's weight can itself be re-delegated - is the one part of the original contract that's easy to get subtly wrong, and this port keeps that chain-walking + cycle-detection logic faithful while swapping mappings for an avl.Tree.
Built for gno 0.9.

Package ballot is a Gno port of the classic Solidity "Ballot" voting contract from the Solidity docs. A chairperson seeds a fixed list of proposals and grants specific addresses the right to vote; each voter can either cast a direct vote or delegate their weight to another voter, and delegation follows a chain so a delegate who later delegates further still carries every accumulated weight. The winning proposal is whichever has the most accumulated weight at query time.
Delegate hands the caller's voting weight to toAddr. If toAddr has already voted, the weight is added directly to that proposal's tally; otherwise it accumulates on toAddr's own weight, ready to be cast (or delegated further) later. Mirrors Solidity's delegation-chain-following with a loop guard.
GiveRightToVote grants voterAddr a voting weight of 1. Only the chairperson may call this, and only for voters who haven't voted yet.
Init configures the ballot exactly once: the caller becomes the chairperson (and is immediately given the right to vote), and proposalNamesCSV — a comma-separated list — seeds the fixed set of proposals. It panics if called twice or with no usable proposal names.
Vote casts the caller's full weight for proposals[proposalIndex].
WinnerName returns the name of the current winning proposal, or "" if the ballot hasn't been initialized.
WinningProposal returns the index of the proposal with the most accumulated weight, breaking ties in favor of the lowest index.
