dfa2regex
Converts Deterministic finite automata to regular expressions.
Example:
Becomes
((1|((ε|0)(ε|0)*1))|((1|((ε|0)(ε|0)*1))((ε|1)|(0(ε|0)*1))*((ε|1)|(0(ε|0)*1))))
Which is automatically simplified to
((0*1)|((0*1)(1?|(0+1))+))
The algorithm itself is short: https://github.com/phiresky/dfa2regex/blob/gh-pages/src/dfa2regex.ts#L108-L116
