A hierarchical tree widget bound directly to a @link TreeStore. Tree contains no child widgets, rather, the tree is rendered based on the models contained in the tree store. Once bound, the tree will remain in sync with the bound tree store.
With state enabled, Tree will save and restore the expand state of the nodes in the tree. A ModelKeyProvider must specified with the TreeStore this tree is bound to. Save and restore works with both local, and asynchronous loading of children.
