Completely new smoother and/or solver class derived from the
base objects in the library may be used without recompiling the
library itself. Once the new smoother/solver class has been
developed, the user can declare a variable of that new type in the
application, and pass that variable to the \verb|p%set(solver,info)|
call; the new solver object is then dynamically included in the
preconditioner structure.
The \verb|what,val| pairs described here are those of the predefined
smoother/solver objects; newly developed solvers may define new pairs
according to their needs.
