trait Source extends Traversable[WikiPage] with Serializable

A source of wiki pages. TODO: do we need this class? Methods that have a paramater with this type are not as flexible as they could be, for example they cannot be called with List(page). The only advantage of this class seems to be the definition hasDefiniteSize = false, which can easily be added to any Traversable implementations that actually need it. We should clearly document in which cases hasDefiniteSize = false is useful or necessary. The Scala documentation doesn't help much here. Traversable also defines all kinds of methods - for example size() - that call foreach() and iterate over the whole collection, which for most of our sources is a huge waste. Even calling head() causes a big overhead, for example a file or a network connection is opened. Is there a more appropriate Scala type?
