  * Second generation of QtQuick treeview.
  *
  * The first one was designed for the chat view. It had a limited number of
  * requirements when it came to QtModel. However it required total control of
  * the layout.
  *
  * This is the opposite use case. The layout is classic, but the model support
  * has to be complete. Performance and lazy loading is also more important.
  *
  * It require less work to write a new treeview than refector the first one to
  * support the additional requirements. In the long run, the first generation
  * could be folded into this widget (if it ever makes sense, otherwise they will
  * keep diverging).
