[Eeglablist] How to keep urevent information even after epoching

[Makoto Miyakoshi]

Dear Antonio,

It is very nice to find out that you used our tools for educational
purpose. EEGLAB was indeed developed for educational purpose, that's what I
heard. If you have comments and/or suggestions, please make your valuable
contributions to this community. Your input is greatly appreciated.
