This looks good, a few minor quibbles but other than those I'll be happy to merge.

The documentation should probably say what happens when D isn't a tournament, is an error thrown, or false returned or an empty list?

<K>false</K> is returned. <P/>

If <K>true</K> is returned, then the vertex, <A>v</A>, is a k-king. <P/>

2-kings in the tournament. If the tournament contains a source, then the
source is the only 2-king (see <Ref Attr="DigraphSources"/>). The number
of 2-kings in a tournament without a source is at least three. A tournament
