The attached test driver, when used with the vault code mentioned
above, shows how the multi_array storage order compares with the
enum dirs{dir_fwd,dir_rev} arg to array_dyn. The comments
at the top summarize the comparison. The output showing
the printouts is also attached.

Maybe one advantage of array_dyn is the ease of rotating the
axes. Another may be offset calculation, because with
array_dyn, no testing is done for the bool values of
general_storage_order::ascending. Instead, an offset
and negative strides achieve the same result, AFAICT.
