Code Sprint 2015-09-01

Our first code sprint was held on September 1-2, 2015 and was hosted at Lawrence Livermore National Laboratories. We had a group of over 20 people that ranged from folks interested in VTK-m to experts in device hardware and software to the core VTK-m developer team. During these two days we tackled many programming challenges. Below is a summary of some of the tasks address and their status at the end of our time.
