    Added interfaces to provide different backends
    
        * Now GXml is based on libxml2 and uses one of
          available possibilities to parse XML files
        * This interfaces will allow to get access to XML
          tree by using different backends parsers
        * Next step is to avoid interfarence with already
          GXml objects definitions
