h3ToGeoBoundary : documentation details

[1chandu]

It seems h3ToGeoBoundary returns an array of vertices, that close the hexagon/pentagon/etc , i.e first and last vertices are same. When it is a hexagon it returns 7 vertices, where first and last are the same. It will be helpful to clarify this in the documentation.

This is documented here - the formatAsGeoJson param, if true, will provide closed loops (i.e. the start and end vertices are the same), as per the GeoJSON spec.
