[Mne_analysis] CSP for multi classification

[JR KING]

Hi,

The object mne.decoding.CSP works with more than 2 classes, but will be
increasingly slow as the number of class increases.

Since CSP is a spatial filtering technique, the more classes you have, the
less you'll be filtering.

You should thus avoid spatial filtering for multi-class problems,
