"""
Run an actuator for a given number of milliseconds to a given position at percentage of max speed in FORWARD or BACKWARDS direction
Key arguments:
duration - Time actuator is in motion, for Servo() objects this can be used to control speed of movement
newPosition - New position between -1 and 1 that actuator should move to
speed - Speed at which actuator moves at, for Servo() objects this parameter is NOT used
direction - Set counter-clockwise (CCW or LINEAR_IN) or clockwise (CW or LINEAR_OUT) as the forward direction
Return Value:
NOTHING
