// The temporal resolution of the acceleration management subsystem. Higher number
// give smoother acceleration but may impact performance
// NOTE: Increasing this parameter will help remove the long slow motion bug at the end
// of very fast de/ac-celerations. This is due to the increased resolution of the 
// acceleration steps that more accurately predicted by the planner exact integration
// of acceleration distance. An efficient solution to this bug is under investigation.
// In general, setting this parameter is high as your system will allow is suggested.
