[Eeglablist] eegplot and TMPREJ

[Max Cantor]

I had a feeling that I was going to need to use global variables, but was
not sure how to do so. I will try writing it into my code as you've shown,
thank you! Likewise, I was definitely planning on saving those rejections
for exactly the reasons you've mentioned.

Thanks!
Max
