    Tracks one direction from a seed.
    
        This function is the main workhorse of the ``LocalTracking`` class defined
        in ``dipy.tracking.local_tracking``.
    
        Parameters
        ----------
        dg : DirectionGetter
            Used to choosing tracking directions.
        sc : StoppingCriterion
            Used to check the streamline status (e.g. endpoint) along path.
        seed_pos : array, float, 1d, (3,)
            First point of the (partial) streamline.
        first_step : array, float, 1d, (3,)
            Initial seeding direction. Used as ``prev_dir`` for selecting the step
            direction from the seed point.
        voxel_size : array, float, 1d, (3,)
            Size of voxels in the data set.
        streamline : array, float, 2d, (N, 3)
            Output of tracking will be put into this array. The length of this
            array, ``N``, will set the maximum allowable length of the streamline.
        step_size : float
            Size of tracking steps in mm if ``fixed_step``.
        fixedstep : int
            If greater than 0, a fixed step_size is used, otherwise a variable
            step size is used.
    
        Returns
        -------
        end : int
            Length of the tracked streamline
        stream_status : StreamlineStatus
            Ending state of the streamlines as determined by the StoppingCriterion.
