<p>Shows a tree, with user-defined icons for some nodes. This tests
listening for tree events. A separate alert is generated upon opening a

closing a folder.</p><p>We also demonstrate changing the default value of
'allowShowPlusMinusSymbol' so that all folders initially have a plus/minus
symbol. Then, upon opening an empty folder, we remove that
icon.</p><p>Lastly, we demonstrate in the alert presented by tree events,
use of the getHierarchy() method to obtain a full "path" for a tree
node.</p>
