renamed "rasterMap" to "Layer"
rename RasterMap to Layer
Created "Layer" class to abstract Raster map functions.
Some refactoring and additional logging.
Generalizing L-Systems, to abstract out the Road-generation system into
it's own ubclass. Eventually I'd like to use the SL-System framework to
generate other stuff (like buildings).
Moving anonymous inner class versions of Conditions and Modifiers out of
RoadmapGenerator, and into their own classes. Probably unnecessary, but
makes the code more maintainable.
Added intrinsic numeric values, so we can get rid of the boolean "only
consider roads" flag in RoadmapGenerator. This is the first step to more
road types.
L-System Module specific to Road system. Part of L-System generalization
effort (long way to go yet).
Bit of refactoring, renaming of methods. Cleaning up.
Spring cleaning.
New package, com.skyline.util. Moved Pair class.
Debugging road system (It's still not working).
