Decodes audio Morse code into text:
% [msg, ToneFreq, ditstat, dahstat] = morseDecode(y, Fs, [ToneFreq])
%
% INPUT
% y - audio signal, [nsmpl, number_of_messages]
% Fs - sampling frequency
% ToneFreq - tone frequency (optional), better be within 30 Hz of the actual one,
% if not set or is empty the actual tone frequency will be estimated
% from the signal, if set to 0, the default 1000 Hz will be used
%
% OUTPUT
% msg - decoded message
% ToneFreq - estimated tone frequency
% ditstat - "dit" interval statistics: [mean, std, min, max]
% dahstat - "dah" interval statistics: [mean, std, min, max]

% Based on decode.m from
