Rountable notes

Matt created better shared pointer memory management in the rendering library.

Ability to strip ghost cells from rectilinear grid has been very helpful.

Matt has been having issues with CUDA builds.

Ken has been having issues on compiling VTK-m on Summit with the XLC compiler. It was not finding the C++11 extensions. Rob says try the 3.14 rc.
