geos-xml-viewer has duplicated functionalities that were already developed in geos-xml-tools to handle XML files.

To do that, multiple steps are required:

• Remove non related XML handling tools from geos-xml-viewer
• Incorporate new features from geos-xml-viewer inside geos-xml-tools
• Clean the new features to make sure they are using already existing functions from geos-xml-tools
• Update geos-xml-tools documentation and create tests
• Update the ParaView plugin called deckReader
• Move deckReader as PVGeosDeckReader to the geos-pv package
• Remove geos-xml-viewer
