/**
 * The AccessibleTableModelChange interface describes a change to
 * the table model.  The attributes of the model change can be
 * obtained by the following methods:
 * <ul>
 * <li> public int getType()
 * <li> public int getFirstRow();
 * <li> public int getLastRow();
 * <li> public int getFirstColumn();
 * <li> public int getLastColumn();
 * </ul>
 * The model change type returned by getType() will be one of:
 * <ul>
 * <li> INSERT - one or more rows and/or columns have been inserted
 * <li> UPDATE - some of the table data has changed
 * <li> DELETE - one or more rows and/or columns have been deleted
 * </ul>
 * The affected area of the table can be determined by the other
 * four methods which specify ranges of rows and columns
