! This routine does two things:
! 1. Computes the transpose of the prolongator Prol and stores
! it explicitly into Restr
! 2. Computes AC = P^T A P
!
! Yes, doing two things at once is against received wisdom, but we are

! This routine does two things:

! 2. Computes AC = P^T A P
!
! Yes, doing two things at once is against received wisdom, but we are
