0011  *      Concrete PDEFoamEvent sub-class.  This foam stores the number             *
0012  *      of events with every cell, as well as the statistical error on            *
0013  *      the event number.  It overrides GetCellValue() for projecting             *
0014  *      the target values given an incomplete event map with                      *
