/** An extension of SimpleTreeModel which implements the
    TreeTableModel interface. It supports a two-column "Name, Value"
    interface and disabling of editing of the "Value" column. Because
    of a bug in the implementation of JTreeTable, it always returns
    "true" for isCellEditable of cells in the "Name" column;
    otherwise, mouse clicks to open handles are not dispatched
    properly. Users are responsible for calling setTreeEditable(false)
    on the JTreeTable to make the names uneditable. */
