new map generator

[paradoxharbinger]

Here is a new map from the generator, with plains (yellow),
forests (green), farmlands (light green), swamps (dark green), mountains (brown), and water (blue). There should be some wastelands in there, but the algorithm is not quite complete.

As of now, I am concentrating my efforts on normal maps, ie the ones that don't wrap around. Once I tweak this to get the wastelands in there I am going to be moving onto to the province boundaries and then to graphics. For the most part, generating the boundaries for the provinces is a generalization of the algorithms used to make the different terrains, so once I get to it, it shouldn't take long to implement.
