Depends on how lightweight you want it to be. There are classes that 
derive from Object, like BoundingBox etc... but if you are going to use 
this data structure the way itk::Point is used, you probably do not want 
anything deriving from itk::Object, cause it will maintain a 
ModificationTime and other overhead...

In that case you could make up your own datastructure
