// Not compiled or tested in-world
// Setup: Put in your own rezzed test object. Put in an animated child; start by touching that child. Owner-touch starts a thirty-sample session; touch again ends early.
// Stop / restore: Automatically stops after thirty samples. Disable/remove to stop; no scene properties are changed.
// Notes: Root movement does not affect the local envelope. Stops if the script prim ceases to be a child; no animation is changed.
