/**************************************************************
*
* CALCULATE NUMBER OF WIDGETS ON PALLET
* ____________________________________________________________
* This program calculates the number of widgets stacked on a
* pallet based on the pallet's weight with and without widgets.
* Each widget weighs 9.2 pounds.
*
* Computation is based on the formula:
* widgetCount = (totalWeight - palletWeight) / 9.2
* ____________________________________________________________
* INPUT
* palletWeight : Weight of the pallet alone (in pounds, as a double)
* totalWeight  : Total weight of pallet with widgets (in pounds, as a double)
*
* PROCESSING
* widgetCount  : Number of widgets stacked on the pallet (as an integer)
*
* OUTPUT
* widgetCount  : The calculated number of widgets
*
