Detailed Description

Two-point correlator for Wilson-type fermions.

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]. unique_ptr is introduced to avoid memory leaks. Add momentum of sink. [21 Mar 2015 Y.Namekawa] Add parameters for output. [27 Jun 2016 Y.Namekawa] Move a funciton global_corr_t() to contract_4spinor.h since this function should always be combined with a function contract_at_t() there. [25 May 2017 Y.Taniguchi]
