Add a MutationObserver for a given element and terminate after `timeout`ms.
@param el DOM element to watch for mutations
@param config MutationObserverInit object (https://developer.mozilla.org/en-US/docs/Web/API/MutationObserver#MutationObserverInit)
@param timeout Number of milliseconds of no mutations after which the observer should be automatically disconnected
If set to a falsy value, the observer will wait indefinitely for Mutations.
@param callback Callback function to call either on timeout or if mutations are detected. The signature of this method is:
function(mutations, callback_data)
Where:
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 - `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()`
Note that the caller should first check to see if `retval.observer` is set before calling `disconnect()` as it may
have been cleared automatically.

How should this work?
0. History changed
- Pass new URL and timestamp of change on to most recent event (which might not have happened yet)
0.1. History changes as a result of a pushState or replaceState
- In this case we get the new URL when the developer calls pushState or replaceState
- we do not know if they plan to make an XHR call or use a dynamic script node, or do nothing interesting
(eg: just make a div visible/invisible)
- we also do not know if they will do this before or after they've called pushState/replaceState
- so our best bet is to check if either an XHR event or an interesting Mutation event happened in the last 50ms,
and if not, then hold on to this state for 50ms to see if an interesting event will happen.
0.2. History changes as a result of the user hitting Back/Forward and we get a window.popstate event
- In this case we get the new URL from location.href when our event listener runs
- we do not know if this event change will result in some interesting network activity or not
- we do not know if the developer's event listener has already run before ours or if it will run in the future
or even if they do have an event listener
- so our best bet is the same as 0.1 above
1. Click initiated
- User clicks on something
- We create a resource with the start time and no URL
- We turn on DOM observer, and wait up to 50 milliseconds for something
- If nothing happens after the timeout, we stop watching and clear the resource without firing the event
- If a history event happened recently/will happen shortly, use the URL as the resource.url
- Else if something uninteresting happens, we extend the timeout for 1 second
- Else if an interesting node is added, we add load and error listeners and turn off the timeout but keep watching
- If we do not have a resource.url, and if this is a script, then we use the script's URL
- Once all listeners have fired, we stop watching, fire the event and clear the resource
2. XHR initiated
- XHR request is sent
- We create a resource with the start time and the request URL
- If a history event happened recently/will happen shortly, use the URL as the resource.url
- We watch for all changes in state (for async requests) and for load (for all requests)
- On load, we turn on DOM observer, and wait up to 50 milliseconds for something
- If something uninteresting happens, we extend the timeout for 1 second
- Else if an interesting node is added, we add load and error listeners and turn off the timeout
- Once all listeners have fired, we stop watching, fire the event and clear the resource
- If nothing happens after the timeout, we stop watching fire the event and clear the resource
3. What about overlap?
3.1. XHR initiated while click watcher is on
- If first click watcher has not detected anything interesting or does not have a URL, abort it
- If the click watcher has detected something interesting and has a URL, then
- Proceed with 2 above.
- concurrently, click stops watching for new resources
- once all resources click is waiting for have completed, fire the event and clear click resource
3.2. click initiated while XHR watcher is on
- Ignore click
3.3. click initiated while click watcher is on
- If first click watcher has not detected anything interesting or does not have a URL, abort it
- Else proceed with parallel resource steps from 3.1 above
3.4. XHR initiated while XHR watcher is on
- Allow anything interesting detected by first XHR watcher to complete and fire event
- Start watching for second XHR and proceed with 2 above.
