Detailed Description

Two-point correlator for Wilson-type fermions.

So far meson correlators were implemented. [4 Feb 2012 H.Matsufuru] Baryon (proton) correlator was implemented by K.Nemuta. This implementation assumes Nc=3, and some of parameters are replaced by explicit numbers. Better performance version: [28 Jul 2012 H.Matsufuru].
