Modules
module	fast3d
	Fast diagonalization methods from NEKTON.

Functions/Subroutines
subroutine, public	fast3d::fd_weights_full (xi, x, n, m, c)
	Compute finite-difference stencil weights for evaluating derivatives up to order $m$ at a point.
subroutine, public	fast3d::semhat (a, b, c, d, z, dgll, jgll, bgl, zgl, dgl, jgl, n, w)
	Generate matrices for single element, 1D operators: a = Laplacian b = diagonal mass matrix c = convection operator b*d d = derivative matrix dgll = derivative matrix, mapping from pressure nodes to velocity jgll = interpolation matrix, mapping from pressure nodes to velocity z = GLL points.
subroutine, public	fast3d::setup_intp (jh, jht, z_to, z_from, n_to, n_from, derivative)
	Compute interpolation weights for points z_to using values at points z_from.
