Detailed Description

A simple strategy for use with LU2x2PreconditionerFactory, that offers static objects for inv(F) and inv(S)

This is a simple startegy for a LU2x2PreconditionerFactory it simply returns statically set RCP pointers to the passed in inv(F) and inv(Schur) operators. Note this will not permit efficient implementations when the preconditioner has to be rebuilt
