Fixed indenting and doxygen comments.
Fixed a few warnings/bugs.
Added edge and surface index for edgeEvalN and surfaceEvalN functions (necessary for wedge interpolation)
Changed order of edges on linear wedge interpolation. Gave tikz figures a more consistent look.
Added basic edge and surface functionality to wedges.
Simplifying code in GuassIntegrationRule
Improved fei3dtrquad and fei2dtrquad interpolations, added 1d gradient damage, fixed warnings.
Added oofem2part for partitioning serial oofem problem into its parallel version
One-point integration allowed for linear brick element.
One-point integration allowed for plane-stress linear quad, documentation fixed.
Filling in some gaps in interpolation classes.
Adding functionality for requestion dof ids of slave dofs. Progress work towards split up ebeNorms.

Renamed fei3dtrlin to fei3dtetlin to avoid confusion.
Setting the number of integration points in planestress2d tests to 4 (to match test results)
Tangent stiffness for damage model implemented, improvements of gradient damage.
Recently added code uncrustified.
Updated to t3dinterface to accept negative (undetermined) mesh size by t3d
Merge branch 'master' of www.oofem.org:/data/git/oofem
Adding custom targets for ctest that runs only tests or only benchmark problems.
