+/* 
+ * 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?
