* \brief Writer ala DOM (Document Object Model)
* \details This class is a non-validating writer, it will only performs well-
* formedness check only.
*
* \details Detailled description here
* To avoid GDCM being yet another broken DICOM lib we try to
* be user level and avoid writing illegal stuff (odd length,
* non-zero value for Item start/end length ...)
* Therefore you cannot (well unless you are really smart) write
* DICOM with even length tag.
* All the checks are consider basics:
* - Correct Meta Information Header (see gdcm::FileMetaInformation)
* - Zero value for Item Length (0xfffe, 0xe00d/0xe0dd)
* - Even length for any elements
* - Alphabetical order for elements (garanteed by design of internals)
* - 32bits VR will be rewritten with 00
*
* \warning
* gdcm::Writer cannot write a DataSet if no SOP Instance UID (0008,0018) is found,
* unless a DICOMDIR is being written out
*
* \see Reader DataSet File
