Performance testing has shown that the combined lower-bounds + update-connectivity
worklet is marginally, but consistently faster than DeviceAdapterAlgorithm::LowerBounds
followed by an update-connectivity worklet. It also requires less memory.
The names of the cell shapes and header files changed superficially. The
check in missed the clip and external faces. Update that code.
There are also some less superficial changes that allow you to manage
cell shapes with tags. It might be worthwhile to update this code to use
that new infrastructure.
