 * TagcollConsumer that serializes its input to an output stream
 * The format of the output is:
 *   lines of "comma+space"-separated items, followed by "colon+space",
 *   followed by the corresponding "comma+space"-separated tags.
 * Examples:
 *   ITEM:
 *   ITEM: TAG
 *   ITEM: TAG1, TAG2, TAG3
 *   ITEM1, ITEM2, ITEM3:
 *   ITEM1, ITEM2, ITEM3: TAG1, TAG2, TAG3
