Re: Review Multi Array

First of all, I think the interface is _really nice_ and the 
architecture seems to be very clean : nice job

but there are still a few things I would like to be more clear :

Complexity guarantees:
I would like to see more elaborate complexity guarantees : what is the 
complexity of indixing in x dimensions using a list of square 
bracket-indices, what about the complexity guarantees of a matrix-view.

Performance :
Along the same line ; The last few weeks there was a discussion about 
the performance and e.g. Ralf W. Grosse-Kunstleven suggested an indexing 
operation that was much more performant compared to the usual list of 
square bracket indices.
As I assume multi-array will be used in numerics, it would also be nice 
to have performance comparisons between multi-array and e.g. blitz++, 
MTL, plain C arrays and fortran.

Relation with MTL and ublas :
Two other matrix-related projects are going on and I think it would be 
good too check what the relation is of multi-array to these before it is 
accepted.
I think it is good that there are sometimes overlapping libraries in 
development as this provides you with invaluable feedback on 
best-practices too achieve a specific goal. But the whole of libraries 
that are accepted inside boost after a review should be consistent and 
should have minimal overlapping while having maximal reused inbetween 
libraries.

documentation:
in the index.html, you have specified anchors that contain a ':'. please 
remove these because e.g. konquerer can not interpret them correctly. So 
  I suggest <a name="sec:dimensions"></a> would become <a 
name="dimensions"></a>
