/**
 * In Excel there are many ways to handle manipulating a workbook based 
 * on some arbitrary user action (onChange, etc).  You use this interface
 * to create classes that will handle the workbook in whatever manner is needed
 * that cannot be handled by POI.
 * <p>
 * For example, suppose that in Excel when you update a cell the workbook
 * does some calculations and updates other cells based on that change.  In
 * ExcelAnt you would set the value of the cell then write your own handler
 * then call that from your Ant task after the set task.
