/**
 * The Smart GWT system supports hierarchical data (also referred to as tree data due to its "branching" organization)
 * with: <ul>   <li> the {@link com.smartgwt.client.widgets.tree.Tree} class, which manipulates hierarchical data sets
 * <li> the TreeGrid widget class, which extends the ListGrid class to visually        present tree data in an
 * expandable/collapsible format.   <li> the ColumnTree widget class, which visually        presents tree data in a
 * so-called         "<a href=http://en.wikipedia.org/wiki/Miller_Columns>Miller Column</a>" format. </ul> For information
 * on DataBinding Trees, see {@link com.smartgwt.client.docs.TreeDataBinding}. <p> A ColumnTree shows a single branch of
 * the underlying {@link com.smartgwt.client.widgets.tree.Tree} horizontally, from  left to right. Thus, the leftmost
 * column shows all the top-level nodes. When the user clicks one of those nodes, a new column is shown immediately to the
 * right of the top-level column, showing the selected node's children. Additional columns are shown as required to present
 * lower-level children. The behavior of ColumnTree is similar to that of the Browser interface in the Apple™
 * iTunes™ application.
