This change implements the `random` function argument. If an argument `random: k` is provided to a dql function then random k results will be returned. For example: `func(has(name), random:5)` will choose 5 random nodes having the name predicate.

There was a problem hiding this comment.
Uids in sg.uidMatrix[i].Uids are not sorted any more. I presume algo.MergeSorted(sg.uidMatrix) requires that.
