Detailed Description

Unpreconditioned H_T kernel continued fraction (5D) operator.

This operator applies the non-hermitian overlap operator Chi = ((1+m_q)/(1-m_q)*gamma_5 + B) . Psi where B is the continued fraction of the pole approx. to eps(H_T(m))

Here, H_T = (b5 + c5) H_w * ( 2 + (b5 - c5) D_w )^(-1) = (b5 + c5) ( 2 + (b5 - c5) D_w^dag )^(-1) * H_w

The denom is multiplied through the 5D system of equations to the RHS
