build cartesian velocity profile for the path

Uses the path to get the cartesian length and the angular distance from start to goal. The trap profile returns uses the longer distance of translational and rotational motion.

		const planning_interface::MotionPlanRequest &	req,
		planning_interface::MotionPlanResponse &	res,
		double	sampling_time = 0.1
	)

generate robot trajectory with given sampling time

Parameters

req	motion plan request
res	motion plan response
sampling_time	sampling time of the generate trajectory
