[boost] Re: [multi] Formal Review Begins

Therefor, I recommend to CONDITIONAL ACCEPT the library with the following conditions:

1. Rename the types so they are intuitive to C++ developers, for example as described above. 2. Remove or generalize (make available to all N) functions currently only available for N =1 (e.g. data()) 3. Make array_ref and subarray the same type. 4. Provide algorithms as free functions. 5. Remove the `extensions()` function if it is the same as a C for-loop. 6. Remove `dynamic_array` or give it a better name like `unique_array`.

Thank you for your review and comments Klemens. Your acceptance conditions are noted. Matt
