This method builds the smoothers and the coarsest-level solvers for the
multilevel preconditioner < code > p< / code > , according to the requirements made by
the user through the methods < code > init< / code > and < code > set< / code > , and based on the aggregation
hierarchy produced by a previous call to < code > hierarchy_build< / code >
(see Section < A HREF = "node21.html#sec:hier_bld" > 6.3< / A > ).
