function test(testdir, n, code)
% Speaker Recognition: Testing Stage
%
% Input:
%       testdir : string name of directory contains all test sound files
%       n       : number of test files in testdir
%       code    : codebooks of all trained speakers
%
% Note:
%       Sound files in testdir is supposed to be: 
%               s1.wav, s2.wav, ..., sn.wav
%
% Example:
%       >> test('C:\data\amintest\', 8, code);
