Detailed Description

template<typename gauge_field, typename DIRAC_OP>
class Hasenbusch_action_1< gauge_field, DIRAC_OP >

The Hasenbusch method for updating fermion fields: Split the Dirac determinant into two parts, D_h1 = D + mh and D_h2 = D * 1 / (D + mh)^dagger

This is the first action term, with D_h1 = D + mh. Since the only real difference here is an addition to the original operator, we can use fermion_action with a different operator.
