ElementChangeWatcher<U extends PheasantTemplate> class

A special extended class of ChangeWatcher used to control the state of not only the PheasantTemplate object, but the Element rendered by the file.

When a state change is caused by the parent, it could refresh the changes on the PheasantTemplate file, including the changes made on the Element and its children elements rendered by the object.

In order to store and reproduce these changes, the ElementChangeWatcher object has added functionality by the HtmlElementStateControl mixin to be able to control the state of children elements that will undergo these state changes.
