Add automaton parser (#1426)
* have compilable program * enable read in file * add hashmap usage * add build hashmap; WIP; test if constructed correctly tomorrow * add testcase to test hashmap * add sorted symbols list * build symbols dictionary * clean up DEBUG * successfully find automaton path * fix all memory leaks * test if automaton same with example * able to iterate through files in a folder * finish testing on one random queue wip - change macro values - add bound checking * add bound checking to program length * add bound checking to program walk length * add boundary check to terminal number, terminal lengths and program length * commit test makefile * add makefile * able to add seeds to gramatron * remove useless argument in automaton_parser * add automaton parser to gramfuzz * change build * revert test.c to original state * add makefile to test.c for testing
