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. This is my own modified version that was originally in Thyra.
