using hypre through petsc

[Barry Smith]

  Matt,

   hypre has a big set of options, we have not written a function
call interface for all of the options. {humm, could we automate this?}
If you wish to do it in the program use the 
PetscOptionsSetValue() routine to add it to the options database
before you set the type to hypre.
