From-string-parsers not tested
Some time ago I broke the EpsilonNFA and MultiInitialStateNFA parsers. There used to be a test of the from-string-parsers that read .txt files in the examples directory. I couldn't find it anymore. Is it still there? Is it broken somehow?
I fixed the EpsilonNFA and MultiInitialStateNFA but it would be nice if from-string-parsing was covered by tests.
