Wrappers designate a Template to call the Module and make it easier (compute cycle-wise) for the Module to know what the incoming parameters are without having to read from scratch. Basicly, it tells the Module that there's no point in trying to read parameters from the Template invocation (ie. ) and that all the good stuff is in the parent frame and not the one passed to getArgs. It's a little different so that it can still be invoked in other ways. Right now, due to backporting limitations, getTitle doesn't work right on Wikia so Lua is not entirely aware of what that parent frame is.
