MSHelicon - Multi-scale Helix convolution (N-dimensional!)

Helicon < in.H filt= ns= jump= adj=0 > out.H

Applies multiscale helix convolution.

from history	integer array	n	reads n1 , n2 , n3 , ...
from par	filename	filt	helix filter file
	integer	adj =0	apply adjoint (backward) filtering
	integer	ns	number of scales
	integer array	jump =0	filter scales
from aux (filt)	integer array	h	helix grid (can be h1 , h2 , ...)
	integer array	lag =1,...,n1	comma separated list of filter lags
	real	a0 =1	zero-lag filter coefficient
