Public Member Functions
void	ConvertStateIDPathintoXYThetaPath (vector< int > stateIDPath, vector< EnvNAVXYTHETALAT3Dpt_t > xythetaPath)
	converts a path given by stateIDs into a sequence of coordinates. Note that since motion primitives are short actions represented as a sequence of points, the path returned by this function contains much more points than the number of points in the input path. The returned coordinates are in meters,meters,radians
