Detailed Description

Internal Overlap-pole operator.

This routine is specific to Wilson fermions!

Chi = (1/2)*((1+m_q) + (1-m_q) * gamma_5 * B) . Psi where B is the pole approx. to eps(H(m))

Internally, it computes Chi = ((1+m_q)/(1-m_q) + gamma_5 * B) . Psi and then rescales at the end to the correct normalization

NOTE: B is hermitian, so
(1 + gamma_5 * B)^dag = (1 + B * gamma_5) = gamma_5 * (1 + gamma_5 * B) * gamma_5
