pyparsing v flex/bison

pyparsing v flex/bison

Actually, updated without some guff

Tokenising longest file I’m likely to need with pyparsing – about 8.5 seconds

Tokenising same file with Flex/Bison – about 0.07 seconds

ie. 2 orders of magnitude speed up.

Of course, Flex/Bison is an order of magnitude more tedious (and involves me understanding strdup and free()).
