* \brief Class for manipulation directories
*
* \note This implementation provide a cross platform implementation
* for manipulating directores: basically traversing directories
* and harvesting files
*
* \note
* will not take into account unix type hidden file
* recursive option will not look into UNIX type hidden directory (those starting with a '.')
*
* \note
* Since python or C# provide there own equivalent implementation,
* in which case gdcm::Directory does not make much sense.
