Symmetric block Gauss-Seidel method with possibly overlapping blocks.
This class implements the step() and Tstep() functions expected by the relaxation concept. They perform a multiplicative Schwarz method on the blocks provided in the block list of AdditionalData in symmetric fashion. Differing from PreconditionBlockSSOR, these blocks may be of varying size, non-contiguous, and overlapping. On the other hand, this class does not implement the preconditioner interface expected by Solver objects.

Implements a transpose vmult operation, which for this class first sets the dst() vector to zero before calling the Tstep() method.
