Fast Simple Class for dealing with 3D bounds.
vtkBoundingBox maintains a 3D axis aligned bounding box. It is very lite weight and many of the member functions are in-lined so its very fast It is not derived from vtkObject so it can be allocated on the stack

Returns 1 if the min and max points of bbox are contained within the bounds of this box, else returns 0.
