public void SuspendCalculations()
This should be used when adding many formulas or modifying large amounts of data on a workbook at once so formulas are not calculated each time cells are dirtied.
For each call to SuspendCalculations, a call to ResumeCalculations must be made. As soon as the number of calls to ResumeCalculations equals the number of calls to SuspendCalculations, calculations will be resumed.
