Began ReflectiveParser2, as an eventual replacement for
ReflectiveParser. Also, removed "Term" in preference for "Symbol". Also,
established Lexeme as a final member of Symbol, with the previous
mechanism exemplified in ReflectiveParser(1) to be used on it instead.
Basically got rid of a bunch of wayward code. Parser needs reworked, I
am no longer entirely certain of what I meant by 'Term' (though I'm
fairly sure a more appropriate name would be 'Symbol', which replaced
it), and 'Lexeme' needs further consideration on its name. (I'm not sure
if I like that, either, but it's certainly JDK-friendly.)
Restructured program to run Scanner through simplified Grammar
enumeration, with a lot of issues removed from its structure. Probably
still a little room for improvement, but much faster now.
