          Args:
              material_id (str): Materials Project material_id (a string,
                  e.g., mp-1234).
              final (bool): Whether to get the final structure, or the initial
                  (pre-relaxation) structure. Defaults to True.
              conventional_unit_cell (bool): Whether to get the standard
                  conventional unit cell
  
          Returns:
              Structure object.
