/**\r
 * This example shows simple checkbox selection in a tree. It is enabled on leaf nodes by\r
 * simply setting `checked: true/false` at the node level.\r
 *\r
 * This example also shows loading an entire tree structure statically in one load call,\r
 * rather than loading each node asynchronously.\r
 *\r
 * The beforecheckchange event is used to veto the taking of a nap.\r
