Added Locking tests demonstrating that shear locking is present in current MPM implementation. Also added some of the same Arenisca/general J2 plasticity benchmarks for Kayenta. -Dave A.

Made changes to serial MPM enforcing a more physically realistic particle speed limiting scheme. Also changed the material model Arenisca.cc to subcycle a minimum of 4 times, as well as delete particles having a jacobian of the deformation gradient larger than 10. -Dave A.

Fixed minor issue with p.scalefactor. Was submitted with indexing from 1 not 0. This resulted in the 3,3 compoenent being garbage. This has been resolved and p.scalefactor is now computed correctly. -Dave A.

Changed p.scalefactor to matrix3 consistent with particle deformation and scaling. Allows use of deformed glyph patch.

Added <exactDeformation> flag for use with prescribed deformation. Requires that max timestep size be set to the largest (and this should be the first) steps size within time_defgrad_rotation or its equivalent. Also set min timestep size to the min within the same prescribed file. This will force the deformation history to be reproduced exactly as outlined in the prescribed fdeformation file. Used with single element histories. Currently the addition of superimposed rotations is not tested with this functionality but is implemented in a consistent manner with the F update.
