[FieldTrip] Markers display with topoplots

[Anne Cheylus]

Dear Emilie,

the layout file biosemi64.lay has changed two years ago, see

https://github.com/fieldtrip/fieldtrip/commits/master/template/layout/biosemi64.lay

the new layout correctly displays Cz at the center of the topoplot.

Because of the old misleading layout, electrodes labelled as Cz, C3 and 
C4 were indeed CPz, CP3 and CP4, see

biosemi64.lay topoplot


All the best,

Anne
