hypre/krylov
History
kolev1 4502255f79 Added two new features to PCG: 
1) A new, residual-based stopping criteria ||r_old - r_new|| < rtol ||b|| which
   is activated with HYPRE_PCGSetResidualTol() and is designed to be used in
   high-accuracy computations with rtol <= 1e-16.

2) HYPRE_PCGSetRecomputeResidual(), which periodically recomputes the residual
   from scratch (r=b-Ax). This, again, can be useful in high-accuracy
   computations, but is potentially expensive and can lead to degraded
   convergence!
