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

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.

Now internal solver uses ||Ax-b||/||b|| instead of ||Ax-b||.

solver_bcgsl.hpp: jump crosses initialization of 'unsigned int i'

solver_test000 now provides nonzero initial solution

Added early exit for internal BiCGStab(l). Added test example based on
#6. Resolved #6 for internal solvers.

Petsc understands common parameters. Support for different option files
for Petsc and Trilinos. Please see files in examples/MatSolve.

Adding CMake installation scripts for library and examples.
find_package(inmost) was not tested.

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)
