I verified that we can read the weight with another processor partition as the one use to compute them.
Small differences appear because of different rounding errors on the individual processors and the core proc who gives his values to the file.

Small change to avoir error when sorted_outareas is smaller than largest_pos (it occurs in Pantanal_n48)

Generalized the code so it could be executed from anywhere.
Created a new test infrastruture.

The fact that performing the sums in different order still induces differences but they are small.

The addition of a landsendtohalo to fetch_basin does not work. Leads to a lock-up in truncate.

But there still seems to be an issue with the calculation of the fetch.

Prepares and tests functions to echange halo and make some operations on core points only (zero and sum).

Corrected some stuff and ensured that the diagnostics from the F90 part are now written into files. This allows for finer diagnostics of the computation there.
