New version of signalPAK (May 15, 2000)

http://users.powernet.co.uk/kienzle/signalPAK

New functions:
   sound, soundsc, __power, rectpuls, resample, czt, lagrange, voice, dB,
   idplot, idsim, mktheta, poly2th, speed_test, test, assert, pretty,
   demo, example, ellipj, ellipke

Deleted functions:
   auplay, power

Interface changes:
   lookup: returns 0 instead of 1 for values before the table
   freqz, grpdelay: accepts vector of frequencies to evaluate
   unwrap: accepts matrices
   stem: makes the struct the basic plot item rather than the circle
   zplane: plots poles and zeros (if given column vectors or matrices) or
        roots of numerator and denominator (if given row vectors)
   interp1: adds 'nearest' and 'poly' interpolation types

Fixes:
   rceps: fix minimum phase reconstruction return value
   triang: fix n=1 case
   cplxpair: fix degenerate cases
   arburg: normalize returned error for length of input
   hilbert: fix return value
   octave-mod.el: to handle test script lines embedded in octave scripts

Maintenance:
   put commas between columns in matrix contants to protect against
        whitespace_in_literal_matrix="ignore"
   add demo and test code to many scripts
   use &&, || instead of &,| where possible
