ref #154

I'm curious, @thewtex, is this a high priority?

Once this is implemented, I can move forward with adding full support for itk-jupyter-widgets in PyVista rather quickly, which it seems a lot of folks are interested in seeing.

That's awesome! I will add initial support as soon as possible (this week) to help you move forward. It will essentially work, but there will be some expected, undesirable behavior -- namely, when visualization parameters, like selection of the color map for scalars, are changed in the interactive browser interface, they will not be updated on the Python side. This will addressed eventually, though.

That sounds fine to me! After all, the PyVista-itkwidgets plotter will be a proof of concept on the first round and then we can refine/refactor it as features are added/fixed.

Thanks for moving so fast on this, @thewtex!!
