// Some reorganisation likely required as both Chroma and IroIro
// are separating the concept of the operator from that of action.
//
// The FermAction contains methods to create 
//
// * Linear operators             (Hermitian and non-hermitian)  .. my LinearOperator
// * System solvers               (Hermitian and non-hermitian)  .. my OperatorFunction
// * MultiShift System solvers    (Hermitian and non-hermitian)  .. my OperatorFunction
