[ Closed ] htmLawed class (OOP code)

Moving to an htmLawed class would be an improvement, but I think there are lower-hanging fruit: Improve the code's readability: more meaningful var names, more comments, less dense syntax; remove the need for global vars (or at least store global state in statics inside global functions); use longer prefix on global functions, e.g. 'htmLawed_' instead of 'hl_'.

The nice thing is none of the above should affect performance, but even if it does, the long term maintainability would be worth it I think.
