LIGGGHTS 2.2.1: (released 13 November 2012)

+ Added a dump atom/vtk command which now enables LIGGGHTS to write to VTK files directly. However, this requires LIGGGHTS to link against VTK libraries, see the new makefile Makefile.ubuntuVTK for an example how to do this. Thanks a lot to Anton Gladky (TU Freiberg) for this contribution.
+ Added a CMake ("Cross Platform Make", build system for LIGGGHTS. Thanks again to Anton Gladky (TU Freiberg) for setting this up.
+ Added the region mesh/tet functionality as it was implemented in LIGGGHTS 1.5.3, also added a tutorial "mesh/tet".
+ Added an auto-check for option atom_modify map array when LIGGGHTS is used in coupling mode. Thanks to Moritz Höfert (BASF) for the motivation for this.
+ Fixed a mesh restart bug introduced in 2.2. Thanks to Tapan Sabuwala (U Illinois) for noting this.
+ Fixed a problem with the shear option for cylinder. thanks to Chris Stoltz (PG) and Kevin Brennan (Perdue) for letting us know about this.
+ Fixed an issue with fix mesh/surface/stress. Thanks to Christian Richter (OVGU Magdeburg) for sending a test-case.
+ Fixed a small issue with shear history continuity across planar faces, when the faces were no direct neighbors.
+ First commit for an implicit integration driver, which should allow to run implicit integration schemes in the future.

However, there are some restrictions in 2.2.1 (see below) which will be relaxed over time:
+ fix breakparticle/force is not yet available
