Inconsistency in Node API

[lintool]

If we look at the Node API, we have:

def randomOutboundNodeSet(numResults: Int, rnd: Random): Seq[Int]:
https://github.com/twitter/cassovary/blob/master/cassovary-core/src/main/scala/com/twitter/cassovary/graph/Node.scala#L123

def outboundNodes(): CSeq[Int]:
https://github.com/twitter/cassovary/blob/master/cassovary-core/src/main/scala/com/twitter/cassovary/graph/Node.scala#L89

Note that one returns a CSeq and the other returns a Seq. Should this be made consistent?

Good catch. Will fix.
