     DM - Abstract PETSc object that manages an abstract grid object

   Level: intermediate

  Concepts: grids, grid refinement

   Notes: The DMDACreate() based object and the DMCompositeCreate() based object are examples of DMs

          Though the DM objects require the petscsnes.h include files the DM library is
    NOT dependent on the SNES or KSP library. In fact, the KSP and SNES libraries depend on
    DM. (This is not great design, but not trivial to fix).

/*MC
  DMRegisterDynamic - Adds a new DM component implementation

  Synopsis:
  PetscErrorCode DMRegisterDynamic(const char *name,const char *path,const char *func_name, PetscErrorCode (*create_func)(DM))

  Not Collective

  Input Parameters:
+ name        - The name of a new user-defined creation routine
. path        - The path (either absolute or relative) of the library containing this routine
. func_name   - The name of routine to create method context
- create_func - The creation routine itself

  Notes:
  DMRegisterDynamic() may be called multiple times to add several user-defined DMs

  If dynamic libraries are used, then the fourth input argument (routine_create) is ignored.

  Sample usage:
.vb
    DMRegisterDynamic("my_da","/home/username/my_lib/lib/libO/solaris/libmy.a", "MyDMCreate", MyDMCreate);
.ve

  Then, your DM type can be chosen with the procedural interface via
.vb
    DMCreate(MPI_Comm, DM *);
    DMSetType(DM,"my_da_name");
.ve
   or at runtime via the option
.vb
    -da_type my_da_name
.ve

  Notes: $PETSC_ARCH occuring in pathname will be replaced with appropriate values.
         If your function is not being put into a shared library then use DMRegister() instead
