1. Verified shifting of displacement histories 2. More attempts at optimization
restore unneeded files for backward compatibility with CVS
moved inc directory into the build tree
1. Some attempts at optimization 2. Fixed writing displacement into fTHKdisp
1. Fixed THK Disp implementation
1. Fixed search algorithm
1. Added code to shift displacement histories if t > t_crit
1. Further changes
1. Further additions to THKDisp3D. Need to add displacement history shifting
1. Continued implementation of THK BC for 3D bridging scale
