[Mne_analysis] ICA code clean up

[Virginie van Wassenhove]

Hi Denis, all,

Great! It would be useful to specify that the color codes for the proposed
k first components irrespective of the predefined choice of max components.

OK, I am glad this is only surface stuff and not a computational issue.

agree

ok, that's reassuring

ok

Explicit selection criteria can't hurt and would be useful if stated
somewhere.

yes

Yep, it is clearer and hope it can be useful for others as well

Thanks very muchly!
