Description:
 def stop_actions(self):
 """ Returns a list of stop actions supported by the motor controller. Possible values are `coast`, `brake` and `hold`. `coast` means that power will be removed from the motor and it will freely coast to a stop. `brake` means that power will be removed from the motor and a passive electrical load will be placed on the motor. This is usually done by shorting the motor terminals together. This load will absorb the energy from the rotation of the motors and cause the motor to stop more quickly than coasting. `hold` does not remove power from the motor. Instead it actively tries to hold the motor at the current position. If an external force tries to turn the motor, the motor will 'push back' to maintain its position. """
