This was a ridiculous argument when we first had it two years ago. I don't
like using the name Picard for the implementation because it doesn't do what
most PDE solver people refer to as Picard. Since both cases are strict
subsets of what mathematicians call Picard, I don't think the name should be
used for that thing in PETSc. Richardson is fine with me.
