% -------- [fh,lh] = multisignalplot(d,varargin) ---------
%
% Plots all of the signals in a data matrix in one figure, separated on the y-axis by a
% the mean(max(data)), or by a user-defined value.
%
% >>> INPUTS >>>
% Required:
% d = data matrix
% Optional:
% Fs = sampling rate...if provided, will plot relative to time on x-axis
% format = 'r','c'...lets the function know if your data is in row or
% column format...by default assumes 'c'.
% col = line color (default 'k');
% maxval = value to separate lines by...default is mean(max(d));
%
% <<< OUTPUTS <<<
% fh = handle to axis
% lh = handle to each line separately
