/**
 * Helper class to generate unique object IDs.
 * It supports two types of IDs: long and short.
 *
 * Long IDs are string GUIDs. They are globally unique and 32-character long.
 *
 * ShortIDs are just 9-digit random numbers. They are not guaranteed be unique.
 *
 * ### Example ###
 *
 *     IdGenerator.nextLong();      // Possible result: "234ab342c56a2b49c2ab42bf23ff991ac"
 *     IdGenerator.nextShort();     // Possible result: "23495247"
