Synopsis
		sfdtw-interp < _in.rsf loc=_loc.rsf > _out.rsf maxshift= exp=2 strain=1.0 n=

program takes traces sampled at arbitrary locations along a 1d line
and outputs regularly sampled line.
program assumes the locations are ordered.

Parameters
		float exp=2 error exponent (g-f)^exp   string loc= auxiliary input file name   int maxshift= maximum shift to be tested   int n= number of traces in output   float strain=1.0 maximum strain for dtw
