CHANGES REQUIRING CODE ADAPTATION
---------------------------------
---------------------------------
* file dune/solvers/norms/diagnorm.hh : class DiagNorm
° introduced template parameters in order to use it with arbitrary matrix blocks
\tparam Diagonal some container type having the random access operator[]; used to store the diagonal entries of the matrix
\tparam VectorType the vector type the norm may be applied to
° old implementation remains as template specialization
---------------------------------------------------------------------------------------
! ° REQUIRED CODE CHANGES: where "DiagNorm" was used, now "DiagNorm<>" is required !
---------------------------------------------------------------------------------------
* file dune/solvers/norms/fullnorm.hh : class FullNorm
° introduced template parameters in order to use it with arbitrary matrix blocks
\tparam LowRankFactor the type of the factor used to represent the low rank operator
\tparam VectorType the vector type the norm may be applied to
° old implementation remains as template specialization
---------------------------------------------------------------------------------------
! ° REQUIRED CODE CHANGES: where "FullNorm" was used, now "FullNorm<>" is required !
---------------------------------------------------------------------------------------
CHANGES POSSIBLY AFFECTING PERFOMANCE (INCLUDING BUGFIXES)
----------------------------------------------------------
----------------------------------------------------------
* file dune/solvers/common/staticmatrixtools.hh
° bugfix for addToDiagonal concerning template specialization
* file dune/solvers/norms/energynorm.hh
° catch slightly negative values of normSquared and return zero instead
° "negativity tolerance" may be set in constructor; default is 1e-10
EXTENSION OF FUNCTIONALITY
--------------------------
--------------------------

FURTHER CHANGES
-------------------------------------
-------------------------------------
