          Args:
              verbosity (int): Verbosity level. Default of 1 includes both
                  direct and cartesian coordinates for all sites, lattice
                  parameters, etc. Useful for reading and for insertion into a
                  database. Set to 0 for an extremely lightweight version
                  that only includes sufficient information to reconstruct the
                  object.
              fmt (str): Specifies a format for the dict. Defaults to None,
                  which is the default format used in pymatgen. Other options
                  include "abivars".
              **kwargs: Allow passing of other kwargs needed for certain
              formats, e.g., "abivars".
  
          Returns:
              JSON serializable dict representation.
