Pretty much, this is a wand that can take anything built on a 16X16 baseplate, save it to a file, and then when you want in again, on a different map, you don't have to rebuild and re-event it. Becuase lets face it, loading saves on a map they didnt start in, is a mess.
So, you load the save file, and a 16X16 baseplate ghost shows up. You plant that baseplate, and it loads the rest of the bricks and their events/emitters/colors/lights/names.
