made FEMConditions set on meshes non-editable to avoid crash ... this should be fixed based on decision if conditions can be set directly on meshes
activated legacy format for geometry data in debug mode
Introduced new CMake-option OGS_PACKAGE_ADDITIONAL_BINARIES.

This makes it easier to package the OGS File Converter into the redistributable
packages.
[AL] Forward additional args for local assembly.
[AL] Overloaded SerialExecutor::execute().

The overloaded version takes a third argument. This argument is used
needed properties in the local assembler.
[AL] Overloaded VectorMatrixAssembler::operator().

The overloaded version has a parameter for data needed by the local assembly process.
[AL] Add SimpleAssembler used for shape matrix initialization.

No local vectors/matrices and no modification of global vector/matrix.
[MGTL] Fix calculation of search length.

In case of aquidistant meshes the expression sum_of_sqr - (sum*sum)/edge_cnt can
get negative due to numerical calculation.  The root of a negative value is not
computable in real numbers.
[MGTL] Added class MeshNodesToPoints.

It is used for conversion of mesh nodes to geometric points required for
visualization.
[MGTL] Add assertion in MeshNodesAlongPolyline().
[ML] Decrease Lis solver default tolerance.

This resolves issues for to high tolerance when applied to matrices with penalty terms from Dirichlet BC.
[ML] Using Eigen notation in GloablDenseMatrix.

Using rows() and cols() instead of getNRows() and getNCols().
[ML] Add FP_T and IDX_T typedefs for LisMatrix
[ML] Comment out matrix size check in GlobalDenseMatrix::add().
[ML] Comment out matrix size check in LisMatrix::add().
Add SimpleTest/FemTests to global cmake.
Add SimpleGroundWaterFlow cmake config.
[2dGWFlow] Add test program body that includes reading of mesh and geo.
Using read fem conditions generating mesh node ids.
Add MeshSubset.
