Veselin Dobrev fd45ae843a Extend the class IterativeSolverMonitor to store a pointer to 
the last IterativeSolver that uses it.

Add a simple ResidualBCMonitor that can be used to check if
essential b.c. are properly imposed on the initial guess, rhs,
operator, and preconditioner.

Andrew T. Barker 0fd9e5218f Add Monitor() calls to MINRESSolver 
I am about 80 percent confident I am passing the "right" residual vector
to the monitor routine.
 2020-04-16 09:11:30 -07:00
Andrew T. Barker d8cd06ea39 Add Monitor() calls to FGMRES and BiCGSTAB 
BiCGSTAB has two residuals, r and s. I have chosen to only monitor r, ignoring
s, but this is an arguable choice.
