<BLOCKQUOTE>A Regular expression class to go with the CSTR EST_String class. 

<P>The regular expression syntax is the FSF syntax used in emacs and
in the FSF String library. This is translated into the syntax supported
by Henry Spensor's regular expression library, this translation is a place
to look if you find regular expressions not matching where expected.
