      Right now $unwind can only unwind an array that is not nested within another array. For example 'a.b' can be unwound in this document:

      { a:{ b:[ 1, 2 ] } }

but not in this one:

{ a:[ { b:1 }, { b:2 } ] }

and not in this one:

{ a:[ { b:[ 1, 2 ] } ] }

      Current behavior is to not unwind anything in these cases.
