Detailed Description

Implements the Epetra_Operator interface with a Thyra LinearOperator.

This enables the use of absrtact Thyra operators in AztecOO as preconditioners and operators, without being rendered into concrete Epetra matrices.

Wrap a Thyra operator in the Epetra_Operator interface, and then wrap it again in a Thyra operator interface.

This lets an arbitrary Thyra operator be given to the Thyra AztecOO adapters.
