          reg_assoc() - A regular pattern substring extractor

          reg_assoc takes a string and explodes it into substrings
          matching the regular expression pattern-strings given in
          pat_arr and associates them with tokens given in tok_arr. If
          def (default 0) is given, it is associated with a non-match.
          The return value is an array of two arrays, the 1st being an
          array of the form

               ({ non-match1, match1, non-match2, match2, ...,
                  non-match n, match n, non-match n+1 })

          and the 2nd holds the tokens corresponding to the matches in
          order:

               ({ def, token corresponding to match1, ...., def,
          token corresponding to match n, def }).

          pat_arr and tok_arr must be of the same sizes, the ith
          element in tok_arr being the corresponding token to the ith
          element of pat_arr. pat_arr can only hold strings.

          If pat_arr (and hence tok_arr) has size 0 then the return
          value is simply ({ ({ str }), ({ def }) }).
