def updatePermIncGrid(self):
        '''
        Update the grid of permanent income levels.  Currently only works for
        infinite horizon models (cycles=0) and lifecycle models (cycles=1).  Not
        clear what to do about cycles>1.  Identical to version in persistent
        shocks model, but pLvl=0 is manually added to the grid (because there is
        no closed form lower-bounding cFunc for pLvl=0).

        Parameters
        ----------
        None

        Returns
        -------
        None
