/**
 * flickcurl_collections_getTree:
 * @fc: flickcurl context
 * @collection_id: The ID of the collection to fetch a tree for, or zero to fetch the root collection. Defaults to zero. (or NULL)
 * @user_id: The ID of the account to fetch the collection tree for. Deafults to the calling user. (or NULL)
 * 
 * Returns a tree (or sub tree) of collections belonging to a given user.
 *
 * Implements flickr.collections.getTree (1.12)
 * 
 * Return value: a collection or NULL on failure
