16: Developer Note:
17: The order of the enum entries is significant, as it corresponds to the canonical numbering
18: of DOFs, and the fact that the numbering starts at 0 may also be used by the implementation.

57: Data structure (C struct), analogous to describing a degree of freedom associated with a `DMSTAG` object,
58: in terms of a global element index in each of up to three directions, a "location" as defined by `DMStagStencilLocation`,
59: and a component number. Primarily for use with `DMStagMatSetValuesStencil()` (compare with use of `MatStencil` with `MatSetValuesStencil()`).

63: Notes:
64: The component (c) field must always be set, even if there is a single component at a given location (in which case c should be set to 0).
