  SweepTwoServos
  By Philip van Allen <philvanallen.com> for the VarSpeedServo.h library (October 2013)
  This example code is in the public domain
  
  Sweep two servos from 0-180, 180-0 in unison
  Uses the wait feature of the 2013 version of VarSpeedServo to start the first servo moving in the background
  and immediately starting a second servo moving and waiting for the second one to finish.
  
  Note that two servos will require more power than is available from the USB port - use an external power supply!
