Detailed Description

Fabric class for CGUzawa.

Caution: As the class CGUzawa requires the submatrices for constructing a solver and not the full matrix, the fabric returns a solver for the system specified at construction time, not for the system specified when asking for a solver. This Trojan Horse behaviour is a workaround.
