The random world generator just assigns terrain and elevations randomly.
SynthesisMethod: make-random-terrain
This method generates completely random terrain. It uses a simple weighting to govern how much of each terrain type appears, and makes random elevations as well.
TerrainTypeProperty: occurrence
n
This property is the percentage of the world that will be of this type,
if the terrain is cell terrain.
If the terrain is border or connection, it is the probability
(expressed as .01% increments) that any direction of any cell
will have that border or connection.
Defaults to 1
