title: Is there a way to programmatically change the value of a UIStepper based on a calculation?
body: <p>Let's say I have 3 <code>UIStepper</code>s.<br>
  When I change the value of one, the values of the other steppers change based on a formula.</p>
  
  <p>Stepper one value is 10.<br>
  Stepper two value is 5.<br>
  Stepper three value is 3.</p>
  
  <p>If I change stepper 10 +/- 1, it might change the value in stepper two +/- one.</p>
  
  <p>Is this possible?</p>
