Corrected iteration over elements and calculation of number of elements
during modification of the mesh.

Corrected that saving meshes with infinity in data can produce bad vtk
files.

Cmake script for superlu will search for blas.

Remove assertions for singular matrices in INNER_MPTILUC since they
could be handled.

Fixed NaN output into vtk files.

Added support for SuperLU (serial) solver.

Copy-paste feature;

Generation of 1d texture for palette for custom color interpolation in
OpenGL;

Gnuplot-stype palette.

Some fixes for previous commit.

Some fixes for code introduced earlier

Dense matrix concatenation.

Joint diagonalization for a set of dense matrices.

Suppression of warnings in automatic differentiation by visual studio.

Backup for nodal and facial MFD methods.

modified DMP correction in ADMFD

Update algorithms for Hessian calculation.

Some fixes for openmp in class residual.

Several algorithms and implementations for hessian calculation.

Fixes for the features introduced in 635cc476 in the case USE_OMP was
not activated in cmake.

Cleanup of Row class and Matrix class.

Significantly reduced memory required for Row class and consequently for
multivar_expression class. Moved out openmp locks and row annotation as
additional service classes.

Introduced classes HessianRow and HessianMatrix for future possibility
of hessian computation in automatic differentiation.

Added class used to store lambda-like expressions within automatic
differentiation.

Added assertions into workaround introduced in f8b3aca2 to check type
sizes during compile time.

LDL^T decomposition of U matrix for optimization in ADMFD example.

Possible workaround for issue #16 with VS2013.

Suppress warning in sparse.cpp with VS2013.

Fixed abs -> fabs in ADMFD example.

Algorithms for removing rows and columns in dense matrices.

Update for MFD example.

Renamed GetDerivative to GetJacobian

Some features for class Residual.

Clean-ups in xml.

Updated MFD.

Adapted ADFVdiscr for Residual class.

Matrix<Var>::DotProduct will promote type depending on the argument.

Changed how matrix annotation is handled to decrease memory required to
store data of type DATA_VARIABLE.

Added multivar_expression_reference that can reference individual matrix
row.

Added Residual class.

Fixed that Sparse::Matrix::Load and Sparse::Vector::Load may required
MPI initialization.

Fix for possibility of race condition in point-to-point MPI
communications.

Fixes for warnings produced by clang.
