I am getting closer to it, as shown in [How to import a .vtu file programmatically? - #2 by CsatiZoltan](https://discourse.kitware.com/t/how-to-import-a-vtu-file-programmatically/1650/2)  
Is there a way to extend (subclassing or other way) `smtk::markup::Import` (the VTK session cannot import a .vtu file, as I noted in my other post) instead of modifying the source code (that way, I would have to be up-to-date with the SMTK git repo)?
