refactoring includes lumping all the coordinate related code together.
create own module for coordinate conversions
should be mostly finished.
fix up some oops'es.
simple use fields pragma for now
more fixes to final state.
fixes
use Geo::MapMaker::CoordinateConverter; remove some warn calls
make more code use the CoordinateConverter.
remove a lot of dead code, use x/y coordinate converter methods
instead of separate x and y ones.
add x/y coordinate converter methods.  these are required to implement
orientation.  also orientation *should* already work now, i think.
support left/top/right/bottom_point.
support an extra_defs property on maps.
