Tahoe Code SVN tahoe

fixed error in use of AutoFill2DT that may affect performance/memory use
during domain decomposition.

skeleton is growing:
o added vector operations headers for 2d/3d
o contact node data class to wrap-up opposing surface info
o added skeleton of 2D enforcement

(1) added Clear() to empty string
(2) corrected translation of UNIX -> MacOS file paths

improved file name handling using StringT

revisions

added an "exit" clause to the subdir make-for-loop-thingie
(forgot waht triggered the GNU.linux.macros commit)

reduce the number of errors in the new code and add a ContactSurfaceT.cpp

A bigger better skeleton* of a quadrature-based contact element framework

*note : skeletons are dead and typically useless.

better exception messaging during WriteOutput

corrected error in trimming string records to ExodusII spec lengths
