/*
 Summary of Parameters to Control Stopping Test:
 - Standard (default) error tolerance: |delta-residual|/|right-hand-side|<tol
 where the norm is an energy norm wrt preconditioner, |r|=sqrt(<Cr,r>).
 - two_norm!=0 means: the norm is the L2 norm, |r|=sqrt(<r,r>)
 - rel_change!=0 means: if pass the other stopping criteria, also check the
 relative change in the solution x.  Pass iff this relative change is small.
 - tol = relative error tolerance, as above
 -a_tol = absolute convergence tolerance (default is 0.0)
   If one desires the convergence test to check the absolute
   convergence tolerance *only*, then set the relative convergence
   tolerance to 0.0.  (The default convergence test is  <C*r,r> <=
   max(relative_tolerance^2 * <C*b, b>, absolute_tolerance^2)
- cf_tol = convergence factor tolerance; if >0 used for special test
  for slow convergence
- stop_crit!=0 means (TO BE PHASED OUT):
  pure absolute error tolerance rather than a pure relative
  error tolerance on the residual.  Never applies if rel_change!=0 or atolf!=0.
 - atolf = absolute error tolerance factor to be used _together_ with the
 relative error tolerance, |delta-residual| / ( atolf + |right-hand-side| ) < tol
  (To BE PHASED OUT)
 - recompute_residual means: when the iteration seems to be converged, recompute the
 residual from scratch (r=b-Ax) and use this new residual to repeat the convergence test.
 This can be expensive, use this only if you have seen a problem with the regular
 residual computation.
  - recompute_residual_p means: recompute the residual from scratch (r=b-Ax)
 every "recompute_residual_p" iterations.  This can be expensive and degrade the
 convergence. Use it only if you have seen a problem with the regular residual
 computation.
