Detailed Description

Standard Conjugate Gradient solver algorithm.

This solver class implements the standard Conjugate Gradient solver algorithm. 22 Dec H.Matsufuru YAML is implemented. [14 Nov 2012 Y.Namekawa] Multi-threaded. [17 Jul 2014 Y.Namekawa] unique_ptr is introduced to avoid memory leaks [21 Mar 2015 Y.Namekawa]
