 * We want each patch to consist of an entire DM, DMDA at first
 - We cannot afford to store much more than the data from a single patch in memory
   - No global PetscSection, only PetscLayout
   - Optional scatters
   * There is a storable coarse level, which will also be a traditional DM (DMDA here)
   * The local and global vectors correspond to a ghosted patch
 * Need a way to activate a patch
   * Jack in sizes for l/g vectors
 - Need routine for viewing a full global vector
 - Jed handles solver
