docs: Convenience constructor for an orthorhombic lattice.
  
          Args:
              a (float): *a* lattice parameter of the orthorhombic cell.
              b (float): *b* lattice parameter of the orthorhombic cell.
              c (float): *c* lattice parameter of the orthorhombic cell.
  
          Returns:
              Orthorhombic lattice of dimensions a x b x c.
