Mesh Watershed

Compute the watershed, initially for the extraction of sulcal pits as described in:
Auzias, G, Brun, L, Deruelle, C, Coulon, O, Deep sulcal landmarks: algorithmic and conceptual improvements in the definition and extraction of sulcal pits, NeuroImage, 2015.

Description

During the flooding, the shallowest basin is merged with the deeper one if R inf thr and D inf ThD;
After the end of the flooding, if A inf ThA then merge the basin with its neighbor with which it shares the longest border.
