<P>
Provides the phone list for words.  A Lexicon is composed of three
 pieces:  an addenda, the compiled form, and the letter to sound
 rules.
 <ul>
   <li>The addenda either contains Word instances that are not in
   the compiled form, or it contains Word instances that replace
   definitions in the compiled form.  The addenda is meant to be
   relatively small (e.g., 10's of words).
   <li>The compiled form is meant to hold a large number of words
   (e.g., 10's of thousands of words) and provide a very efficient
   means for finding those words.
   <li>The letter to sound rules will attempt to find a definition for
   a word not found in either the addenda or compiled form.
 </ul>
