Hey! Great template engine! More faster than original jresig micro-templating.

It would be nice to have some comments explaining the lines... I've been playing around with this gist and (in a very extreme case of a overly complex template), I had a problem with a string containing the % sign inside the script part of a template. I could get it to work by changing the line 6 to:

        .replace(/'(?=[^]*%>)/g,"\t")

(Note that I just removed the % sign), but I have no clue how it may affect other templates. Apparently nothing else broke. What exactly does this line do?

Cheers!
