Functions/Subroutines
integer function, public	grid_utilities::calc_xyz_grid (grid_eq, grid_xyz, x, y, z, l, r)
	Calculates \(X\), \(Y\) and \(Z\) on a grid grid_XYZ, determined through its E(quilibrium) coordinates.
integer function, public	grid_utilities::extend_grid_f (grid_in, grid_ext, grid_eq, n_theta_plot, n_zeta_plot, lim_theta_plot, lim_zeta_plot)
	Extend a grid angularly.
integer function, public	grid_utilities::copy_grid (grid_a, grid_b, lims_b, i_lim)
	Copy a grid A to a new grid B, that was not yet initialized.
integer function, public	grid_utilities::calc_int_vol (ang_1, ang_2, norm, j, f, f_int)
	Calculates volume integral on a 3D grid.
integer function, public	grid_utilities::trim_grid (grid_in, grid_out, norm_id)
