Spatial three pdm and four pdm can be dump onto disk during the
calculation. "disk_dump_pdm" should be used. Since spin three pdm and
four pdm are not as useful as spatial three pdm and four pdm. They are
not stored by default. "store_spinpdm" can be used to store them on
disk.
Change in the Documentation of particle density matrix.
And minor changes for nonspinadapted npdm.
