A Regular expression class to go with the CSTR EST_String class.
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.
