/**
   The STRING class packages a character string which has
   been allocated in a hash table.  All strings in this 
   table are unique.  As a result, string comparison can
   be done my comparing the string pointers.

   The usage of this class assumes that the string has been
   entered in the string table.  If the text field is initialized
   with a string, make sure that the string is entered in the
   string table (find_string can be called with a STRING 
   argument, in which case it will make a copy of the string
   pointed to by text).

   This class is used by the string table hash table in
   strtable.h
