FS#335 - inconsistent verbose parameter of solvers
User who did this - Markus Blatt (mblatt)

----------
First of all: overlappingschwarz.hh contains no solvers but just preconditioners, which in general do not support any verbosity level.

Second of all: SuperLu differs from all other solvers as it is a direct solver. Therefore the behaviour of verbose versus nonverbose mode is different anyway.

And last but not least:

The constructor is generally not regarded as an interface method. Different solvers might need different parameters (e.g. a Matrix or a LinearOperator and even additional parameters etc.)

What one could and probably should do is to introduce a method setVerbosityLevel(int) or similar to give the user a uniform way to accomplish verbosity for all solvers.
