This evaluator supports building and traversing NFA's based on Regular Expressions that support the following actions:
a + b(union)ab(concatenation)a*(Kleene star)
// NFA representing the RE: ((a + b)c)*
Nfa* a = Nfa::simple("a");
Nfa* b = Nfa::simple("b");
Nfa* c = Nfa::simple("c");
a->unite(b);
a->concatenate(c);
a->star();
// Run strings on the Nfa
a->isValidString("acbc", false); // returns true
a->isValidString("acacacac", false); // returns true
a->isValidString("xyz", false); // returns falseThe booleans being passed into isValidString determine whether the evaluation should occur in parallel or not.
NOTE: Parallel evaluation is currently broken
