Revert Button 
  - Definition:
 The revert button returns the values of the parameters in the Setup Panel to the values corresponding with the current running
    simulation. This is useful if you realize you've made a mistake in entering new
    parameters. It lets you go back to the values that you know already work.
 
- Usage:
 Note that the
    parameters will be changed back to their previous values when you press the revert button,
    but no changes take effect until you press the Restart button.
