Hello!

Currently it is not possible to pass shape() of one multi_array into 
constuctor of another:

    boost::multi_array<float, 2> a;
    boost::multi_array<float, 2> b(a.shape());

This is because shape() returns size_t const* and multi_array check in 
constructor that ExtendList satisfy CollectionConcept. size_t const* 
don't satisfy this concept.

I'm going to allow constructor of multi_array to get both size_t const* 
and size_t const[]. So I'm going to replace extents.begin() with 
boost::begin(extents).

What should I do with concept check?
