Fill Sinks algorithm

A commandline tool to run an algorithm proposed by Wang & Liu, which processes digital elevation models (DEMs) and fills surface depressions in them.

In addition this tool supports setting a minimum slope argument which is found in other open-source implementations (QGIS, SAGA GIS).
