#149: add attribute NX_class="NXroot" to NXroot NXDL

    Type:  defect       |      Status:  new             
Priority:  minor        |   Milestone:  release NXDL 1.0
Keywords:               |  
------------------------+---------------------------------------------------
 From a discussion in the code repository, there is an inconsistency with
 the definition of {{{NXroot}}}.  It seems that NeXus data files need an
 attribute at the root level declaring the root node '''is''' {{{NXroot}}}.

 To avoid invalidating existing NeXus data files, this attribute will be
 added as optional to NXroot.
