/**
 * Requests Motion Magic® to target a final velocity using a motion profile. 
 * This allows smooth transitions between velocity set points.  Users can
 * optionally provide a duty cycle feedforward.
 * 
 * Motion Magic® Velocity produces a motion profile in real-time while attempting to honor the specified
 * Acceleration and (optional) Jerk.  This control mode does not use the CruiseVelocity, Expo_kV, or Expo_kA
 * configs.
 * 
 * If the specified acceleration is zero, the Acceleration under Motion Magic® configuration parameter is used
 * instead.  This allows for runtime adjustment of acceleration for advanced users.  Jerk is also specified in
 * the Motion Magic® persistent configuration values.  If Jerk is set to zero, Motion Magic® will produce a
 * trapezoidal acceleration profile.
 * 
 * Target velocity can also be changed on-the-fly and Motion Magic® will do its best to adjust the profile. 
 * This control mode is duty cycle based, so relevant closed-loop gains will use fractional duty cycle for the
 * numerator:  +1.0 represents full forward output.
