Fast multidimensional Arrays

[rikki cattermole via Digitalmars-d-learn]

Okay looks like I've made a boo boo and ldc is compiling out that entire 
multiplication loop out.

Its passing the array statically and since its never assigned back, its 
just never compiled in (unless you specify it via ref).

So, this is where I give up as it is 2am.

Perhaps try and make it parallel (std.parallemism can help hugely).
