Finally implemented perceptual brightness thing.

% scope - arrow to create scrolling plot of real valued signals
%
% scope ::
%    W:natural ~'width of plot in samples',
% -> arrow({[[N,1]]}, {}, pair([[N,W]],pair(empty,empty))).
%
% If input vectors are N dimensional, this will plot
% N lines showing their history over the last W samples.


function b=scope(width,varargin)
	b=awindow(width,nan)*arr(@transpose)*plotter(varargin{:});
