+(the AxisArray) that knows about its dimension names and axis values.  This
+allows for indexing by name without incurring any runtime overhead.  This
+permits one to implement algorithms that are oblivious to the storage order of
+the underlying arrays.  AxisArrays can also be indexed by the values along their
+axes, allowing column names or interval selections.")
