David Lonie started this week on VTK-m. He is working on refactoring exceptions.

Rob has been working on the merge of VTK and VTK-m.

Found a problem with the gradient filter that is using an int division instead of a floating point division.

Found and fixing some problems with the TBB device. As part of this, we are updating the device testing code to ensure that the TBB tests actually run multiple threads.

Matt is continuing a refactor of the ray tracing to allow lower level access.
