 Rename "lexing" to "parsing" since really we have moved way beyond a simple
 lexing/tokenization strategy.

-The rules are currently confusingly implemented, and have poor performance when
-used in deeply nested grammars.
-
-We need to refactor lex2 so that rules have two methods:
-
-1. match():
-This method should return whether or not the rule can match the current input
-that the lexer is lexing. If its result is true, the result will be passed
-(along with the lexer, etc.) to the rule's lex() method. Otherwise, the next
-rule will be tried.
-
-2. lex():
-This method is a generator, which is expected to return one or more tokens. In
-addition to the arguments given to match() it will be passed the result of the
-call to match() (which is guaranteed to be true, and will most often be a
-re.Match object). As all generators, this method will raise StopIteration when
-there are no more tokens to return, and will raise LexError if there are other
-problems.
