geo support in bleve

First, all of this geo code is a Go adaptation of the Lucene 5.3.2 sandbox geo support.

Notes

• All of the APIs will use float64 for lon/lat values.
• When describing a point in function arguments or return values, we always use the order lon, lat.
• High level APIs will use TopLeft and BottomRight to describe bounding boxes. This may not map cleanly to min/max lon/lat when crossing the dateline. The lower level APIs will use min/max lon/lat and require the higher-level code to split boxes accordingly.
