function [X,I] = ascii2xi(datafile,labelfile,dlm)
% ASCII2XI loads data from ASCII files.
%  [X,I] = ascii2xi(datafile,labelfile,dlm)
%
% ACII2XI loads labeled data from ASCII files of
%   following format:
%   Data file 'datafile': 
%     - each row corresponds to one pattern. 
%     - each columns corresponds to one feature.
%     - columns are separated by given delimiter 'dlm'
%       (blank space is default).
%
%   File of labels 'labelfile':
%     - contains one column of integers corresponding to
%       rows in the data file.
%
% Input:
%   datafile [string] data file.
%   labelfile [string] file with labels.
%
% Output:
%   X [D x M] matrix containing loaded patterns, where D is 
%      dimenssion and M is the number of patterns.
%   I [1 x M] vector containing labels.
