I must confess that I had given a glimpse at the multi_array feature,
because it looked exactly like the kind of stuff that I needed to
represent the grid, but I had discarded it because I would need to
access my data mostly to run vector algebraic operations, and
multi-array doesn't seem to have any BLAS feature.

Basically what I need is something like a multi_array for storage,
and a way to expose its various slices as ublas vectors.

Now, although boost currently doesn't seem to have anything of the sort
(unless I missed it), I'd be more than happy to contribute something myself,
but I'm pretty sure it needs some deep understanding of boost internals,
which I currently don't possess.
