[gradsusr] correlation map

[Stefano Materia]

Dear Bernd,
tcorr requires the first variable to be only function of time (if not, you
get an error message such as: "Error from TCORR:  1st arg must be 0-D").
I would like both the variables to be function of space as well, in order
to obtain a map of time correlations.

I hope this clarify my question.

Thanks for your help,
Stefano
