* ChineseGrammaticalRelations is a

* Examples are from CTB_001.fid

* Currently, we have an external data structure that stores information about
* whether a relation is universal or not, but that should probably be moved
* into GrammaticalRelation.
*
* TODO(pliang): add an option to produce trees which use only the USD
* relations rather than the more specialized Chinese ones.
