Functions/Subroutines
integer function, dimension(3), public	pw_grid_info::pw_grid_init_setup (hmat, cutoff, spherical, odd, fft_usage, ncommensurate, icommensurate, ref_grid, n_orig)
	...
integer function, dimension(3), public	pw_grid_info::pw_grid_n_for_fft (n, odd)
	returns the closest number of points >= n, on which you can perform ffts
integer function, dimension(2, 3), public	pw_grid_info::pw_grid_bounds_from_n (npts)
	returns the bounds that distribute n points evenly around 0
real(kind=dp) function, public	pw_grid_info::pw_find_cutoff (npts, h_inv)
	Given a grid and a box, calculate the corresponding cutoff *** This routine calculates the cutoff in MOMENTUM UNITS! ***.
