Two reasons: 1. Provide unit test without requiring Epetra, etc. 2. Using SIMPLE nested inside Hierarchical Block Gauss-Seidel presents a better test of this capability
… Block Gauss-Seidel - This is required to prevent hitting a later assertion

Motivation: this is meant to enable a user solving a monolithic multiphysics problem with Navier-Stokes to employ SIMPLE/SIMPLEC for the the uvwp sub-system and use Block Gauss-Seidel everywhere else.
For a N-S system with a single extra DOF, for example, we can employ SIMPLEC for the uvwp term and combine it with the remaining DOF through another layer of Block Gauss-Seidel:
Theoretically, this should also allow us to do arbitrary levels of nesting for Schur-complement type solves, but I certainly haven't tested that.
