Hydro-analysis

hydro-analysis provides functions for Hydrology DEM manipulation. There are a couple generic functions for reading/writing raster files of any common primative type (which surprizingly I couldn’t find anywhere else, unless you use GDAL which I am trying to avoid). Also there are a couple functions based on whitebox. Whitebox is a command line tool, this provides functionality via functions so can be called from your code.
