/**
 * A Deliberator takes in a poll's Tally,
 * which holds the amount of judgments of each grade received by each Proposal,
 * and outputs that poll's Result, that is the final rank of each Proposal.
 * 
 * Ranks start at 1 ("best"), and increment towards "worst".
 * Two proposal may share the same rank, in extreme equality cases.
 * 
 * This is the main API of this library.
 * 
 * See MajorityJudgmentDeliberator for an implementation.
 * One could implement other deliberators, such as:
 * - CentralJudgmentDeliberator
 * - UsualJudgmentDeliberator
