-- The purpose of this class is to have something that can be passed into callbacks that
-- demand a "Player" object as a parameter and hopefully prevent the mods that have
-- registered with those callbacks from crashing on a nil dereference or bad function
-- call. This is not supposed to be a remotely functional thing, it's just supposed
-- to provide dummy methods and return values of the correct data type for anything that
-- might ignore the false "is_player()" return and go ahead and try to use this thing
-- anyway.
-- I'm trying to patch holes in bad mod programming, essentially. If a mod is so badly
-- programmed that it crashes anyway there's not a lot else I can do on my end of things.
