Added multilevel version of crout-ilu solver with maximum product
transversal preordering on each level. The multilevel version is based
on condition number estimation, factorization of rows with large
condition number or small diagonal is postponed for the next level.

Fixes for near-zero values in maximum product transversal algorithm and
negative path-length.

Fixes for output in DrawMatrix, option for text-based output for small
matrices.

GRDECL reader - check time steps are not negative, write well direction.

MPTILUC - prevent out of memory access for singular matrices.

Thanks to Olga Fuks

Cmake script for superlu will search for blas.

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

Some fixes for code introduced earlier

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

Fixes for warnings produced by clang.

Fixed bug in auto-differentiation that would calculate incorrect weights
for derivatives in ad_val().
Adapted several geometrical and adjacency retrieval algorithms to handle
broken conformity of the grid during modification, more attention to the
problem is needed.
Added visual studio debugger helpers.
Fixed several issues with openmp support.
Added openmp parallelization of BiCGStab(L) solver.
Fixed issues that files overwritten with MPI_File* functionality may
contain previous information.
Fixed a bug in OctreeCutcell, added another example for it.
Fixed a bug in collective operations in mesh class.

Restored OctreeCutcell example;
Added FixEdgeOrder, CheckEdgeOrder algorithms to check of consistency of
2d elements;
Element::Connect now uses FixEdgeOrder for faces;
Automatic grid dimension detection for vtk;
Fixed bug that sets may contain invalid links to elements even after
ApplyModification;
Corrected condition estimator in ddpqiluc;
Switched off pseudoinverse in bicgstab(l) since svd algorithm is bad.

Fixed svd for bcgstab(l);
Transposed matvec;
Interfaces for collective operations for Mesh class.

Pseudoinverse for polynomial matrix in bicgstab(l) to improve stability
(as in petsc);
Added RowMerger class for sum of sparse rows.

Synchronizing various changes

Made database file case insensitive.
Tinkered dropping rules in INNER_MLILUC.
Added rule for git to ignore svn presence.
Added google analytics pixel to main page.

Replaced russian comments in doxygen.
Examples with OpenGL would not lead to error in cmake if no library is
found.

Fixed incorrect writing of sets data.
Returned ||Ax-b|| norm to solver.

Changed default parameters.
Fixed bug for trilinos-aztec, when non-converged solution was accepted.
Enchanced dropping rules in INNER_MLILUC solver.

fixes for issue #1

Fixes for gcc and intel compilers.
gcc-4.1 clean with -Wall -Wextra
intel 11.1 clean with -Wcheck -w1
msvc2010 gives one unrelated warning

Huge update involving update of underlying data representation and
elements management. Different interaction with iterators. New
ElementSet representation.  Some annotation for documentation is added.
New data structures. Examples require update. (check
examples/CMakeLists.txt)
