+ * Class DOMNodeList.
+ *
+ * This is a fake DOMNodeList class that allows adding items to the list. The original class is static and the nodes
+ * are defined automagically when instantiating it. This fake version behaves exactly the same way but adds the function
+ * add() that allows to insert new DOMNodes into the DOMNodeList.
+ *
+ * It cannot extend the original DOMNodeList class because the functionality behind the property ->length is hidden
+ * from the user and cannot be extended, changed, or tweaked.
