The trace of deviatoric tensor must be zero but is
linearly scaling with the tensor's norm.

[Jenkins] Added warnings parser

Add ode system preAssemble() call.

In some processes (using non-local methods, for example)
the assembly is split in two parts: computation of local
quantities and actual (non-local) assembly (integration)
into the local matrices.

Extend addTest macro

This allows for more precise control of the comparisons.

[Test] Corrected the new permeability input for one benchmark

Avoids a conversion warning.

Rewrite quadratic mesh generator

Same tests but only counting number of nodes fulfilling
specific criteria, not relying on fixed mesh numbering.

Small fixes

... after formatting in #1983.

Restructure LIE SD and HM processes

* reimplemented raster to mesh conversion

* fixed index issues and added 3d index calculation

* added necessary changes to gui dialogue

* added tests

* clang format

* added ifdef for data explorer/vtk includes

* modified dereferencing of unique pointers, formatting

* changed pointer to vector in vtk prep

* using const& for nodes vec

* fixed remaining occurences of dereferencing raster object

instead of detJ * integralMeasure * weightedPoint.weight().

As in all other processes.

Those are empty classes with constructors just relaying data to
the SmallDeformationLocalAssembler* class constructors.

The DisplacementDim is always equal to GlobalDim.

Along the changes choose the 'int' version as everywhere else.

Also move some code from the header files to the cpp, cleanup
instantiations.
