More flex

I have been doing some more work on the HTML parser to see if I could improve the speed a bit. I decided to change yyin to read from a file rather than stdin and this has made quite a difference to the speed. It is now faster than HTML::Parser (but its not as functional or tidy)
My next task is to either find a good extendable hashing library for C or call C++ std libs from C. I have never had to do this before so it could be fun. I need to be able to use either C’s equivalent to the C++ standard map and non standard hash.
So far I have not had much luck finding a C hash library that fits the bill..
