Detailed Description

This action goes to a given ArPose very naively.

This action naively drives straight towards a given ArPose. The action stops the robot when it has travelled the distance that that pose is away. It travels at 'speed' mm/sec.

You can give it a new goal pose with setGoal(), cancel its movement with cancelGoal(), and see if it got there with haveAchievedGoal().

For arguments to the goals and encoder goals you can tell it to go backwards by calling them with the backwards parameter true. If you set the justDistance to true it will only really care about having driven the distance, if false it'll try to get to the spot you wanted within close distance.

This doesn't avoid obstacles or anything, you could add have an obstacle avoidance ArAction at a higher priority to try to do this. (For truly intelligent navigation, see the ARNL and SONARNL software libraries.)

	Gets the goal the action has.
double	getSpeed (void)
	Gets the speed the action will travel to the goal at (mm/sec).
bool	haveAchievedGoal (void)
	Sees if the goal has been achieved.
void	setCloseDist (double closeDist=100)
	Sets how close we have to get if we're not in just distance mode.
void	setEncoderGoal (ArPose encoderGoal, bool backwards=false, bool justDistance=true)
	Sets a new goal and sets the action to go there.
void	setEncoderGoalRel (double dist, double deltaHeading, bool backwards=false, bool justDistance=true)
	Sets the goal in a relative way.
void	setGoal (ArPose goal, bool backwards=false, bool justDistance=true)
