Detailed Description

Typically, tags which have an end tag will create and later render a list of child nodes.

This class contains API such as append and render to make creating such list easily.

The findChildren method behaves similarly to the QObject::findChildren method, returning a list of nodes of a particular type from the Node objects contained in the list (and their children).
