Adjacency type.

\note This type is used to identify adjacency directions with

easily understandable keywords (left, right, up, etc.) and is thus

mainly useful for `Orthtree_traits_2` and `Orthtree_traits_3`. In

higher dimensions, such keywords do not exist and this type is

simply an integer. Conversions from this integer to bitsets still
|

work but do not provide any easier API for adjacency selection.
