[Mne_analysis] filling gaps between a set of concatenated labels

[Denis-Alexander Engemann]

The best thing would be to compute a "smooth" enveolope around the
outermost vertices and just take everything inside. I fear this is not as
easy to get as it sounds ...
Anyways, on closer inspection, the actual amount of vertices disjoint by th
gaps is neglegible. I might not suffer enough to look into it.

Alex, have we ever thought about adding some set logic to labels? I'm
thinking of overloading the minus operator for example.
