Detailed Description

CGNR solver.

solve D x = b by (Ddag D) x = b' and b' = Ddag b.

delegate to base CG solver. NB. iter displayed by vout.detailed does not give #mult of D but #mult of DdagD

Introduce unique_ptr to avoid memory leaks. [21 Mar 2015 Y.Namekawa] Add flop_count. [ 8 Aug 2016 Y.Namekawa]
