* mutations is the list of mutations detected by the observer or `undefined` if the observer timed out
* callback_data is the passed in `callback_data` parameter without modifications
*
* The callback function may return a falsy value to disconnect the observer after it returns, or a truthy value to
* keep watching for mutations. If the return value is numeric and greater than 0, then this will be the new timeout
* if it is boolean instead, then the timeout will not fire any more so the caller MUST call disconnect() at some point
* @param callback_data Any data to be passed to the callback function as its second parameter
* @param callback_ctx An object that represents the `this` object of the `callback` method. Leave unset the callback function is not a method of an object
*
* @returns {?object} - `null` if a MutationObserver could not be created OR
* - An object containing the observer and the timer object:
* { observer: <MutationObserver>, timer: <Timeout Timer if any> }
*
* The caller can use this to disconnect the observer at any point by calling `retval.observer.disconnect()`
