The multi_array fits in very nicely with MTL 3. The container of
containers flavor of interface is the same for MTL 3 matrices, as is the
way array views work.

There is no overlap between multi_array and MTL 3. multi_array is a multi
dimensional container, not a numeric (linear algebra) entity. However,
multi_array will be an important building block in creating various
numeric entities. These numeric entities (including the element-wise
operators that everyone is interested in) will come along as separate
libraries as people implement them. There may need to be some small
changes to multi_array to accomodate them, but the changes should only
need to be additions.

Ron's approach of first submitting a multi_array without the numeric
operators is the right approach because:

1) it is easier for the Boost membership to review one small component
  at a time. ("small" here is a relative term)

2) There are many non-numeric uses for multi-dimensional containers.

Cheers,
Jeremy
