 * ============================================================
 * AUCT TOKENIZER
 * ============================================================
 *
 * Auct is treated as an encoding rather than a collection
 * of string replacements.
 *
 * Latin is scanned from left to right.
 *
 * At every position, the parser attempts to find the longest
 * known Latin token.
 *
 * Example:
 *
 *     "philosophia"
 *
 * becomes:
 *
 *     ph | i | l | o | s | o | ph | i | a
 *
 * rather than:
 *
 *     p | h | i | ...
 *
 * This is what allows combinations to have priority.
