August 22 2014: Parser building state machines
	parser:

	Converted the parser back to using a stack, this time operand b
	is loaded off first followed by the operand, followed by operand
	a. The new order seems to maintain the intended meaning a bit
	better.

	css.bnf:

	Modified to test the two baic operations, Alternate and
	concatenate.

Next: Implement parentheses ordering.
