The Paris Saclay logo isn't clickable.

Extremely minor issue, but in the first cell of solar_wind_starting_kit.ipynb
[<img src=\"http://project.inria.fr/saclaycds/files/2017/02/logoUPSayPlusCDS_990.png\" width=\"70%\">](http://www.datascience-paris-saclay.fr)
should instead be
<a href="http://www.datascience-paris-saclay.fr"><img src="http://project.inria.fr/saclaycds/files/2017/02/logoUPSayPlusCDS_990.png" width="70%"></a>
for the link to be clickable, since it's written in HTML.
