+Version Log:
+
+0.6, February 2014:
+ First MPI version. MPI capability is working and mostly
+ optimized; MPI+OpenMP is working but needs optimization.
+ Replaced GMV mesh reader with internal mesh generators.
+ Added QCS velocity difference routine to reflect a recent
+ bugfix in FLAG. Increased size of big test problems.
+
+0.5, May 2013:
+ Further optimizations.
+
+0.4, January 2013:
+ First open-source release. Fixed a bug in QCS and added some
+ optimizations. Added Sedov and Leblanc test problems, and some
+ new input keywords to support them.
+
+0.3, July 2012:
+ Added OpenMP pragmas and point chunk processing. Modified physics
+ state arrays to be flat arrays instead of STL vectors.
+
+0.2, June 2012:
+ Added side chunk processing. Miscellaneous minor cleanup.
+
+0.1, March 2012:
+ Initial release, internal LANL only.
