// <synopsis>
// This class is a specialization of the abstract base class
// <linkto class=DataConversion>DataConversion</linkto>.
// It contains functions to copy data without conversion.
// <p>
// This class exists to make it possible to use a <src>DataConversion</src>
// object when no conversion is actually needed.
// </synopsis>
// <example>
// See example in class <linkto class=DataConversion>DataConversion</linkto>.
// </example>
// <motivation>
// This class makes it possible to use the conversion framework
// for operations where a conversion is only a simple copy.
// </motivation>
// <todo asof="$DATE$">
// <li> Support data type long double.
