Content hierarchy accessed through Content bean

The content hierarchy is a tree of content nodes. Content nodes can be labels, compositions, and links. Compositions are also called pages. Links can be internal or external. In the GUI, links represent the nodes in the Favorites list. Internal links point to a portal page, external links can point to any URL.
