BoundingBox
Represents an area bounded by a northeast and southwest.
A GeoJSON object MAY have a member named "bbox" to include information on the coordinate range for its Geometries, Features, or FeatureCollections.
When serialized, a BoundingBox is represented as an array of length 2*n where n is the number of dimensions represented in the contained geometries, with all axes of the most southwesterly point followed by all axes of the northeasterly point. The axes order of a BoundingBox follow the axes order of geometries.
For the BoundingBox to be serialized in 3D form, both Positions must have a defined altitude.
