/**
 * TreeTableModel is the model used by a JTreeTable. It extends TreeModel to add

 * TreeTableModel may have. Each column, like a column in a TableModel, has a
 * name and a type associated with it. Each node in the TreeTableModel can
 * return a valunmne for each of the columns and set that value if isCellEditable()
 * returns true.
