+switch off Octree example - not compiling on windows

+prevent heap overflow due to big arrays in OldDrawGrid

Automatically switch off packages in cmake when related libraries are not found

operator () that return data in matrix form for TagRealArray and
TagVariableArray

Fix dot product of dense matrices, introduce submatrix operator for
dense matrices that allows to manipulate data in part of the matrix.

Do not store automatizator reference in dynamic_variable.

When only PERMX is provided in GRDECL file, consider it as scalar
permeability.

Simple test for int32 overflow testing in nnz count for fcbiilu2

Conflicts:
	Examples/Octree/main_test.cpp

Do not build Octree when opengl was not found.

Constant correctness for dense matrices.

Refinement into cube and sphere in AdaptiveMesh for specific tests with
MFD-ES

Restricted communication of geometrical parameters when exchanging
parts of the mesh between processors.

Added function MarkNormalOrientation to detect situation when ghost
faces are oriented opposite to shared face on owner processor.

Corrected MFD-ES to account for orientation at ghost faces and to flip
sign of normal velocity component on ghost faces when it is known to
differ on master face on owner processor.

Added test for MFD scheme as projection step for Navier-Stokes problem
with analytic solution of Ethier-Steinman

warning #858: type qualifier on return type is meaningless

Classes  AnnotationService, Vector, Row in inmost_sparse.h

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.
