arguments and options and to improve Matlab compatibility.

----------------------------------------------------------
** The following window functions now accept a Matlab compatible option
to select the periodic variant, useful for FFT applications:

===============================================================================
signal-1.3.0 Release Date: 2014-01-26 Release Manager: Mike Miller
===============================================================================
** The following functions are new:
digitrevorder upsamplefill
primitive wconv
ultrwin
** Several bugs have been fixed in the following functions:
ellipord ifwht
findpeaks remez
fir1 resample
fwht schtrig
grpdelay zp2sos
** Replaced line continuation marker "\" by "..." to avoid deprecated syntax
warning in Octave 3.8.
** The signal package now depends on Octave 3.8 or newer. The `ellipke'
function is required, which used to be provided by the specfun package.
Consequently, the signal package no longer depends on specfun.
===============================================================================
signal-1.2.2 Release Date: 2013-03-25 Release Manager: Mike Miller
===============================================================================
** No change release to correct bad file permissions on previous release.
===============================================================================
signal-1.2.1 Release Date: 2013-03-17 Release Manager: Mike Miller
===============================================================================
** The following functions are new:
buttap
cheb1ap
cheb2ap
ellipap
findpeaks
fwht
ifwht
** Improved Matlab compatibility for the following window functions:
barthannwin
blackmanharris
blackmannuttall
chebwin
flattopwin
nuttallwin
The changes include always returning a column vector, returning a valid
window for a length argument of 1, and making all arguments after the
length optional.
** Minor updates to documentation for the following functions:
cpsd
mscohere
sos2tf
sos2zp
tfestimate
zp2sos
** signal is no longer dependent on the optim package.
===============================================================================
signal-1.2.0 Release Date: 2012-09-21 Release Manager: Carnë Draug
===============================================================================
** Improved Matlab compability for the function `fir2'. This changes include
always returning vaues in a row (even when the smoothing window is a single
column), the default values for grid_n and ramp_n, and returning an error
when invalid values are used (instead of silently adjusting them).
** Fixed failing tests for the following functions:
fir1 pei_tseng_notch residued
** The function `rceps' was fixed to work correctly with odd-length inputs.
** Bugfix in `xcorr2' introduced in 1.1.2 that would not accept "none" as
scale option.
** `xcorr2' scaling option "coeff" was changed to return the normalized
cross-correlation.
** The following functions are new:
movingrms schtrig clustersegment
** signal is no longer dependent on the image package.
** signal is now dependent on the general package.
===============================================================================
signal-1.1.3 Release Date: 2012-05-12 Release Manager: Carnë Draug
===============================================================================
** signal is no longer dependent on the audio package.
** signal is now dependent on the image package.
** The function `marcumq' was imported from the communications package and has
been completely rewritten to improve performance and fix computational
errors.
** Package is no longer automatically loaded.
** The functions `__ellip_ws' and `__ellip_ws_min' have been removed (they
are now subfunctions of `ncauer'.
** The function `blackmanharris' was fixed to have even symmetry.
