Prototyping of projection conversion & spatial indexing routines.

Rough work in progress, but just to cover the bases, some of the formulas are borrowed from Leaflet.

• Figure out how MKMapPoint is setup
• projected meters/map point/coordinate translations
• scale/zoom translations
• pixel width for zoom
• meters/pixel at given latitude & zoom
• Spherical Mercator
• Mercator (ellipsoid)
• CGPoint/coordinate translations
• distance formulas
  • Spherical Cosines
  • Haversine
  • Apple/Core Location passthrough
• nearest neighbor
  • Apple/Core Location passthrough
  • S2
  • R-Tree
  • Quad tree
• rotation transforms
