Dumping of FSM has been rewritten in DOT language.

Dumped FSMs look like the following.
(After passing this through 'dot' it is obvious that some states are dangling. E.g. in "NFA for: /^.$/" states 1 and 7 can not be reached from initial state 9.)

```dot

    "initial"[shape="plaintext",label="NFA for: /^.$/"]
