The user's shell matrix _will_ be usable by either Petsc or Epetra...
they're going to call the ShellMatrix interface functions.
The trouble is that you have to put the petsc and epetra specific stuff
_somewhere_. For instance with Petsc... where are you going to call
MatCreateShell()? That's the type of stuff I was intending to be in
Petsc/EpetraShellMatrix. Again, this directly mirrors what happens with
NonlinearSolver...
