* An adapter object that casts a [const itk::XxxContainer] into [const std::xxx]
* and enables access to the underlying data structure.
* The class is provided for interface consistency with STLContainerAdaptor
* plus the [const] modifier. Since everything is const, there is no need to call
* AdapteeType::Modified() in the destructor.
* Here's a usage example of STLContainerAdaptor
* itk::STLConstContainerAdaptor<itk::VectorContainer<unsigned long, ElementType>> vecAdaptor(aContainer);
* const std::vector<ElementType> & vec = vecAdaptor.GetSTLContainerRef();
* // do things with vec ...
