Add feature to calculate a Layout based on fabric width.
A Layout on fabric is called a 'Marker'.
User indicates if fabric has a 'nap' (one-way direction) or a 'repeat' (horizontal stripe, vertical stripe, or plaid (both horizontal and vertical)).
User indicates in Detail mode the grainline of each workpiece.
The workpieces are arranged so that each workpiece's grainline matches the grainline of the fabric.
Once the Marker is generated, the yardage can be calculated and displayed.
