MustNewFromPolygons is like NewFromPolygons except on error it will panic.

NewHitMap will return a Polygon Hit map, a Ordered Hit Map, or a nil Hit map based on the geomtry type.

NewFromPolygons assumes that the outer ring of each polygon is inside, and each inner ring is inside.

NewOrderdHM will add the provided hitmaps in reverse order so that the last hit map is always tried first.

PolygonHM implements a basic hit map that gives the label for a point based on the order of the rings.

always will return the label for the point.

PolygonHMSliceByAreaDec will allow you to sort a slice of PolygonHM in decending order.

OrderedHM will iterate through a set of HitMaps looking for the first one to return inside, if none of the hitmaps return inside it will return outside.
