/**
 * Provides a list or tree of {@link com.smartgwt.client.widgets.layout.NavItem navigation items}, each of which specifies
 * a component to be displayed in a mutually exclusive fashion in the {@link
 * com.smartgwt.client.widgets.layout.NavPanel#getNavDeck navDeck}. <p> A NavPanel can either have a flat list of
 * <code>NavItems</code> or a hierarchy via {@link com.smartgwt.client.widgets.layout.NavItem#getItems NavItem.items} - use
 * {@link com.smartgwt.client.widgets.layout.NavPanel#getIsTree isTree} to explicitly control this. <p> Because NavPanel
 * extends {@link com.smartgwt.client.widgets.layout.SplitPane}, it automatically shifts between side-by-side vs single
 * panel display on handset-sized devices.  Specifically, the {@link com.smartgwt.client.widgets.layout.NavPanel#getNavGrid
 * navGrid} is set as the {@link com.smartgwt.client.widgets.layout.SplitPane#getNavigationPane SplitPane.navigationPane}
 * and the {@link com.smartgwt.client.widgets.layout.NavPanel#getNavDeck navDeck} is set as the {@link
 * com.smartgwt.client.widgets.layout.SplitPane#getDetailPane SplitPane.detailPane}. <p> Note that <code>NavPanel</code> is
 * a fairly simple component to replicate by composing other Smart GWT widgets.  If you need a component that looks roughly
 * like a <code>NavPanel</code> but will require lots of visual and behavioral customization, consider using the underlying
 * components directly instead of deeply customizing the <code>NavPanel</code> class.  A <code>NavPanel</code> is
 * essentially just a {@link com.smartgwt.client.widgets.tree.TreeGrid} and {@link com.smartgwt.client.widgets.layout.Deck}
 * in a {@link com.smartgwt.client.widgets.layout.SplitPane}, with a {@link
 * com.smartgwt.client.widgets.grid.ListGrid#recordClick recordClick} handler to call {@link
 * com.smartgwt.client.widgets.layout.Deck#setCurrentPane Deck.setCurrentPane()} with a component ID stored as an attribute
 * of each Record.
