Doxygen comments for Automatizator class.

Some additional features for Automatizator class: copy/assignment, list
tags, unregister tag.

Fix compilation issue with Octree example on newer gcc.

Fixes for mesh modification algorithms

A lib for general adaptive mesh

Fix errors when any of USE_AUTODIFF, USE_SOLVER, USE_MESH or
USE_PARTITIONER are disabled.

Consistent checks for presence of global ids and use of global ids in
communications between shared and ghost elements in parallel.

Simplified octree example without GUI.

thanks to Andrey @SilverLife

Made all algorithms for matrices abstract from matrix implementation.

Added few algorithms:
Solve - find A*X=B with A and B matrices
PseudoSolve - find X=A^+*B using singular value decomposition.
Kronecker product
operator / for B^{-1}*A
operator *= for in-place multiplication

Added ability to specify storage type for Matrix, allows for
Matrix<Storage::real,Storage::real_array> or
Matrix<Storage::var,Storage::var_array> to directly manipulate data
stored in the mesh.

Class SubMatrix with full matrix functionality to address and
manipulate some submatrix in original matrix.

Fully commented in doxygen inmost_dense.h.

Silence solver initializer when database file provided as “”.

Silence solvers complaints about parameters.

Updates for Tests/solver_test001

Disable TagVariable and TagVariableArray when USE_AUTODIFF is disabled.

Fixes for Octree example.

Added some doxygen comments into inmost_dense.h

Added comments to Element::Boundary

Handy replacement for Tag class that provide data access through square
brackets.

# SolverPETSc cmake file case sensitive
# SuperLU segmentation fault fixed
# Trilinos enumeration namespace fixed
# Examples mpi off fixed

If second line in vtk file equals  "VTK_OUTPUT_FACES file is written by
INMOST"
indicates that there are property values stored also on faces

Fix input/output of empty dense data with xml file format.

Fix parsing empty parentheses as vector with zero entries in xml files.

Fix modification algorithm.

Fix vector graphics output in OldDrawGrid

Add exposition of mesh by material in OldDrawGrid

Few switches in solver to handle large mechanics matrices

1)SetParameter for fcbiilu2
2) deleted void*

Fix for procedure merging hessians and multiplication of jacobins

Few more unit tests for hessian

Fix hessian calculation for sqrt and add unit test

Fix hessian calculation for sin and cos operations.

Added few unit tests for automatic differentiation

Member functions in iterators for remote_reference_array were private.
