sig=erb2log(sig,cfs)

% method of class @signal
% function sig=erb2log(sig,cfs)
%
% changes the signal (that is ususally a function of frequencies, into
% another signal with frequencies, but now the spacing is according to the
% cf list in cfs. All points are interpolated
%
%   INPUT VALUES:
%       sig: original @signal
%       cfs: list of frequencies
% 
%   RETURN VALUE:
%       sig: new @signal
