ZBitmap

Copperbox revision 483.

I've added a new module Traverse that does column/row traversals (i.e. zig zig). The important part of this is actually that it makes the coordinate system explicit with a newtype wrapper. For instance the arrays in Chalkboard have Cartesian coordinates, whereas the arrays in .bmp files have 'C array' coordinates. Next step - I'll rewrite the existing traversals in ZBitmap with the new scheme.
