function [ varargout ] = readEyelink( file , mode )
%READEYELINK function returns a structure containing data from a .asc
% Eyelink file.
%
% [ structure ] = readEyelink( 'name_of_the_file' , 'mode_name' )
%
% INPUTS
% 1. file is the name of a .asc Eyelink file
% 2. mode can be :
% - 'Numeric' (default), for a numeric array of all events
% - 'Array', for arrays seperating all events
% - 'Raw', for a cell containing each lines of the file
% - 'All' = 'Numeric' + 'Array' + 'Raw'
%
% OUTPUTS
% 1. Structure containing data from a .asc
% Eyelink file.
%
% NOTES
% 1. If there is no input argument, the functons open a UI to select the
% file to read.
% 2. If there is no mode as input argument, the function uses the default
% mode (numeric).
% 3. The function takes less than 1 minutes to read a 10 minutes record
% from the Eyelink (1000 Hz, monocular).
