Expand all tree nodes

You can use Tree.expandAll to expand tree nodes at multiple levels. Use this only for tree views that contain relatively few nodes; otherwise the process of expanding all nodes may take a long time, and the user will not be able to perform other tasks while the tree is updating.

For example, suppose the tree has these levels: Country, City, Property, Building, Lease; you can do the following:

Expand all nodes at levels:

tree.expandAll();

Expand all nodes on levels up to the Building level, so that buildings are visible, but leases are not:

tree.expandAll(3); // up to level 3, 0-based
