/**
* \class DefaultPixelAccessor
* \brief Give access to partial aspects a type
*
* DefaultPixelAccessor is templated over an internal type and an
* external type representation. This class encapsulates a
* customized convertion between the internal and external
* type representations.
*
* PixelAccessor is the class responsible for pixel-to-pixel
* transformation during image data access. The DefaultPixelAccessor
* is an identity operation on the pixel value. It only exist in
* order to standarize the way in which pixels are accessed.
*
* PixelAccessor are used by ImageAdaptors in order to present
* an Image as being of a different type. The usual application
* of ImageAccessors is Image casting, by avoiding the overhead
* of an ImageFilter that performs the complete transformation
