Maplat Core library

Maplat is the cool Historical Map/Illustrated Map Viewer API.
It can transform each map coordinates with nonlinear but homeomorphic projection and makes possible that the maps can collaborate with GPS/accurate maps, without distorting original maps.
This is part of Maplat project.
