[Eeglablist] Envtopo image for one group only

Let me confirm what happened to support you better.
std_envtopo outputs all combination of conditions x groups by default.
If this does not contains what you want, and you still want to have
one group only... do you want something like 'the main effect of
group' for each level of group?
