<DL>
<DD>Full constructor.  This constructor accepts a LHS non terminal,
  an array of RHS parts (including terminals, non terminals, and 
  actions), and a string for a final reduce action.   It does several
  manipulations in the process of  creating a production object.
  After some validity checking it translates labels that appear in
  actions into code for accessing objects on the runtime parse stack.
  It them merges adjacent actions if they appear and moves any trailing
  action into the final reduce actions string.  Next it removes any
  embedded actions by factoring them out with new action productions.  
  Finally it assigns a unique index to the production.<p>

  Factoring out of actions is accomplished by creating new "hidden"
  non terminals.  For example if the production was originally: <pre>
    A ::= B {action} C D
  </pre>
  then it is factored into two productions:<pre>
    A ::= B X C D
    X ::= {action}
  </pre> 
  (where X is a unique new non terminal).  This has the effect of placing
  all actions at the end where they can be handled as part of a reduce by
  the parser.
