Description:
 def adsorb_both_surfaces(self, molecule, repeat=None, min_lw=5.0, reorient=True, find_args={}):
 """ Function that generates all adsorption structures for a given molecular adsorbate on both surfaces of a slab. This is useful for calculating surface energy where both surfaces need to be equivalent or if we want to calculate nonpolar systems. Args: molecule (Molecule):
 molecule corresponding to adsorbate repeat (3-tuple or list):
 repeat argument for supercell generation min_lw (float):
 minimum length and width of the slab, only used if repeat is None reorient (bool):
 flag on whether or not to reorient adsorbate along the miller index find_args (dict):
 dictionary of arguments to be passed to the call to self.find_adsorption_sites, e.g. {"distance":2.0} """
