 * The TreeNodeModel class represents a single TreeNodeModel for the treeview. Actually, this renders the real UI.
 *
 * The component needs this input value:
 *
 * * @Input() node: AcTextTreeNode;
 *
 * The several options are set through the AcTreeNodeOptions object that is being held by the
 * AcTextTreeNode class. This includes colors, icons, and other styles.
 *
 * The component can fire these events:
 *
 * * @Output() nodeClick: EventEmitter<AcTreeNode>;
 * * @Output() checkChanged: EventEmitter<AcTreeNode>;
 * * @Output() selectedChanged: EventEmitter<AcTreeNode>;
 * * @Output() collapseChanged: EventEmitter<AcTreeNode>;
