/** \class SimpleDataObjectDecorator
* \brief Decorates any "simple" data type (data types without smart pointers) with a DataObject API
*
* SimpleDataObjectDecorator decorates an object with a DataObject
* API. This allows simple objects to be encapsulated into objects
* that can be passed as down the pipeline. This decorator is intended
* to be used on native types (float, int, etc.) or any objects not
* derived from itkObject. To decorate a subclass of itkObject, see
* DataObjectDecorator.
*
* The decorator provides two methods Set() and Get() to access the
* decorated object (referred internally as the component).
*
* Note that when an instance of SimpleDataObjectDecorator is created,
* the component is initialized with its default constructor.
*
* SimpleDataObjectDecorator can decorate any simple data type. Two
* other decorators are provided for decorating pointers.
* DataObjectDecorator will decorate pointers to subclasses of
* itkObject (internally storing the pointer in a
* SmartPointer). AutoPointerDataObjectDecorator will decorate any
* other pointer and manage the memory deallocationg of the component.
