/** \class EuclideanDistanceMetricWithMissingValuePow2
* \brief Euclidean comparison distance function facing missing value. The square root is not performed in this class.
*
* This class is derived from EuclideanDistanceMetric class. In addition
* to the initial Evaluate method, the class does not perform calculation
* when a component does not contain any data. The 'no data' case is perform through the \code SetToMissingValue() \endcode
* which performs a \code Nan \endcode affectation.
*
* The class can be templated over any container that holds data elements, as
* for template of EuclideanDistanceMetric.
*
* The only restriction is that elements have to support NaN values.
