// This data structure can be used to represent coarse bounds of objects, in situations where detailed triangle-level
// computations can be avoided. In physics systems, bounding boxes are used as an efficient early-out test for geometry
// intersection queries.
// the 'Axis-aligned' part in the name means that the local axes of this bounding box are restricted to align with the
// axes of the world space coordinate system. This makes computation involving AABB's very fast, since AABB's cannot
// be arbitrarily oriented in the space with respect to each other.
// If you need to represent a box in 3D space with arbitrary orientation, see the class OBB. */
