Buffer #387

I have implemented turf.buffer around a polygon with a distance of 50 metres and the polygon returned varies in size between 30 - 50 metres approx greater than the original.

This is because buffer operations are non-geodesic. The current implementation is only capable of flat-plane buffers. It is a known limitation I would love to fix when I have the time, but it is a significant algorithmic lift.
