Detailed Description

The linear solver a timestepper uses when the application does not name one.

Lives here rather than in common/linear_algebra.hh on purpose: the solvers sit above the linear-algebra layer, so naming them from common/ would invert the include order and become a cycle the first time a solver header wants is_distributed_la.
