Renamed sequence classes to avoid clashes with seq methods;
Fixed default slicing dimension while retaining behaviour of window.m;
Updated use of sequences in dsp/synth.

function y=zeropad(n,x)
% ZEROPAD - Function to zero pad a signal
%
% y=zeropad(n,x) : adds n zeros to head and tail of signal
% If n<=0, y=x;

if n>0,
	y=[zeros(n,1); x(:); zeros(n,1)];
else
	y=x(:);
