[Eeglablist] Channel Locations for BioSemi

[Vincent LeBlanc]

Hi Enzo!
Sorry for the delay, I wanted to verify my settings before sending you
something that's not what I'm using right now.
I used the included dipfit model and took what you said in consideration.
It makes a lot more sense now =)

Thanks again!!
