Removed jQuery dep. Added 4 (!) more deps in the process, but I think it's worth it. What do you think?
(Also, there were some errors in the example.html file, which I've fixed.)
BTW, if you don't care about IE <= 8, we could get rid of the 'get-by-class' and 'event' dependency. I don't care about it too much. Your call.
jQuery removed via #32 (just merged)
