 * This type represents a group of rules which a validator checks. For now, the only grouping is by
 * speed: if a set of rules can be checked quickly, it will be included in the PASS_FAST group,
 * otherwise, it is grouped in the PASS_FULL group.
 * 
 * In future, this could be extended to include severities. To be able to group by severity helps
 * with the MessageLimitException. A validator should report errors first, and then warnings, and
 * then infos, in order to avoid the message limit being reached before the most severe problems are
 * reported.
