slowly getting to the bottom of some horrible automata bugs
fixed problems adding transitions
transitions hold the actual src and dst stated, not their id
fixed bugs to make nfa_copy tests pass
fixed problems with nfa_eval-test
undoing a transition now calls rewind() on the evalstream
added a large, thurough, complicated test to nfa_eval-test
added a newline to the end of nfa_eval.c
will now build the project with symbols
fixed nfa_parsing_eval-test to reflect new parsing eval behavior
merged new lines at end of files
