   **
   **      Rules are made up of four parts:
   **
   **              The left context.
   **              The text to match.
   **              The right context.
   **              The phonemes to substitute for the matched text.
   **
   **      Procedure:
   **
   **              Seperate each block of letters (apostrophes included)
   **              and add a space on each side.  For each unmatched
   **              letter in the word, look through the rules where the
   **              text to match starts with the letter in the word.  If
   **              the text to match is found and the right and left
   **              context patterns also match, output the phonemes for
   **              that rule and skip to the next unmatched letter.
   **
   **
   **      Special Context Symbols:
   **
   **              #       One or more vowels
   **              :       Zero or more consonants
   **              ^       One consonant.
   **              .       One of B, D, V, G, J, L, M, N, R, W or Z (voiced
   **                      consonants)
   **              %       One of ER, E, ES, ED, ING, ELY (a suffix)
   **                      (Found in right context only)
   **              +       One of E, I or Y (a "front" vowel)
