Title: finish adding and testing ingroup metadata for trees

This should generate an ingroup annotation for a tree when one node is tagged as ingroup. If more than one node is tagged it will choose the ancestor if the nodes are in an ancestor-descendent relationship; otherwise one will be chosen arbitrarily. The metadata tag is ot:inGroupClade.
