/*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
