Started on Asg 3. Grammar is good for now. Shift/reduce conflicts
occur but end up being ok due to Bison's auto handling by shift.
Changed main to call yyparse()
Changed makefile run: to have -ly flags

TODO:
	Do actions. Need to create AST NODE for each nonterminal
	Arrange terminals using adopt
added file that is test3.oc pre ran through cpp
so that I can look at the actual source when debugging
