Clim user manual

I would suggest to add this comment in the Clim user manual:

"The Clim function computes a climatologie over the startdates covered by the whole experiments/observational data sets. It means that the startdates not available for all the data (model and obs) is excluded when computing the climatologies."

I think it is really important to provide such information. In my case, I was very surprised to find different climatologies and anomalies for a same experiment loaded several times with different other experiments.

Cheers
