Stuff I do not like in ANTLR 3 prototype
The stateCounter is not thread safe and I have to set it in weird
external ways when testing and such. Perhaps make a state number for
testing as well as one for other stuff.
I wonder about the names of Node, Graph etc... Do I need DFANode as separate than NFANode? Should it be DFAState and NFAState not node?
What about BitSet vs LSet? Why have both?
Should we hook up states pointing to each other with pointers or should we store int indexes into a numberToState table and deference via the array to get to an actual node?
Make args (DFANode vs IntArrayList) more consistent in NFA->DFA conversion routines.
