Map File Spec.

Here's where the real fun starts :) !

The map files will be of the size:

[(number of tiles) x (4 bytes)] + 8 bytes

The first two 32 bit ints will be the width and height respectively.  The rest is an array of 32 bit ints representing the tiles.

Here's the breakdown:

-4 bits represent the main tile type

-15 bits represent different things depending on the main type


   -12 bits for "smoothers" on coastlines

   -3 bits for river moouths


   -5 bits for road and railroad

   -5 bits for river

   -2 bits irrigation, farming, mining

   -1 pollution

   -1 hut

-2 bits for resources

That leaves 11 bits to play with
