//! How votes will be recounted will depend on policies set in previous [`Initialize()`] call.
//! 4. Use [`AddVote()`] to add a vote from users.
//! 5. Check [`GetStatus()`] after either [`UpdatePotentialVoters()`] or [`AddVote()`] calls to
//! check whether voting has concluded.

//! see if the voting has concluded.
//! Once voting has concluded, the result cannot be changed, so you can release the reference
