/*
* this object provides a way to manipulate the parent-patches arguments (and name!)
* usage:
* + put this object into an abstraction
* + put the abstraction in a patch
* + send the object a _list_ of arguments
* + the next time the patch (wherein the abstraction that holds this object lives)
* is saved, it will be saved with the new arguments instead of the old ones!
* - example: "list 2 3 4" will save the object as [<absname> 2 3 4]
* + you can also change the abstraction name itself by using a selector other than "list"
* - example: "bonkers 8 9" will save the object as [bonkers 8 9] regardless of it's original name
* - use with care!
*
* nice, eh?
