[phobos] array() function

[David Simcha]

I wrote this when I was cleaning up array().  The use case for it is 
that, in generic code, you generally assume that calling array() on a 
range will result in you receiving a random access range.  This makes 
that assumption valid even for narrow strings.  In other words, it 
eliminates an ugly special case.
