% function EEG = code2bin(EEG, keeptype)
%
% Converts captured numeric event codes into BinLabel
%
%  Note: very preliminary alfa version. Only for testing purpose. May  2008
%
%  HELP PENDING for this function
%  Write erplab at workspace for help
%
% Inputs:
%
%   EEG       - input dataset
% keeptype    - 1 = keeps unmatched event codes in EEG.event.type after code2bin
%               convertion.
%             - 0 = delete unmatched event codes.
%
%
% Outputs:
%
%   EEG       - output dataset
