Subject: [PATCH] Adding :

std::string TranslateToKey(guint16 group, guint16 element);
(because a tag key may not be associated to a dictionary)

int gdcmHeader::CheckIfExistByNumber(guint16 Group, guint16 Elem);
(we need to know if we want to build a kosher Dicom Header)

int gdcmElValSet::CheckIfExistByNumber(guint16 Group, guint16 Elem);
Well .... private fields *do* exist in C++
