DomListener monitors the DOM and invokes callbacks when modifications occur.

DomListener works by registering a global MutationObserver on the body tag and collects all childList events for his subtree. All mutation events are queued and processed on a reqAnimationFrame. Registered nodes are held with weak references, and will be garbage collected when out of scope.
