def draw(self, **kwargs):

        Returns a new position obtained after `n_steps` of HMC simulation.

        Parameters
        ----------
        kwargs: dictionary
            The `kwargs` dictionary is passed to the shared variable
            (self.positions) `get_value()` function.  For example, to avoid
            copying the shared variable value, consider passing `borrow=True`.

        Returns
        -------
        rval: numpy matrix
            Numpy matrix whose of dimensions similar to `initial_position`.
