AztecOO objects to implement the Thyra::LinearOpWithSolveBase and Thyra::LinearOpWithSolveFactoryBase interfaces. The subclass Thyra::AztecOOLinearOpWithSolveFactory should be used by clients to manage the creation of Thyra::LinearOpWithSolveBase objects from Thyra::EpetraLinearOpBase objects.
See this testing program for how these adapters are used to take an Epetra_CrsMatrix and us it to create these linear solver objects.
