/**
 * Title:        Calc Count Record
 * Description:  Specifies the maximum times the gui should perform a formula
 *               recalculation.  For instance: in the case a formula includes
 *               cells that are themselves a result of a formula and a value
 *               changes.  This is essentially a failsafe against an infinate
 *               loop in the event the formulas are not independant. <P>
