Explain value 100 in eroding DEM expression

[wenzeslaus]

Provide reasoning for the value 100 in Compute new DEM with erosion carved-in in the Erosion modeling (hydrology_erosion.html) assignment.

r.mapcalc "elev_erodedb_1m = elev_lid792_1m-(soillossbare_1m/100.)"

Additionally, consider changing the value.

This was an ad hoc value purely for visualization purposes- feel free to
change it, the proper value along with the units may be in the related pdf
or in the erosion paper with Michael Barton (Isaac spent some time figuring
it out for different conditions)
