+-- 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.
