860    Instantiating a tr_torrent had gotten more complicated as features were
861    added.  At one point there were four functions to check metainfo and five
862    to create tr_torrent.
863
864    To remedy this, a Torrent Constructor (struct tr_ctor) has been introduced:
865    - Simplifies the API to two functions: tr_torrentParse() and tr_torrentNew()
866    - You can set the fields you want; the system sets defaults for the rest.
867    - You can specify whether or not your fields should supercede resume's.
868    - We can add new features to tr_ctor without breaking tr_torrentNew()'s API.
869
870    All the tr_ctor{Get,Set}*() functions with a return value return
871    an error number, or zero if no error occurred.
872
873    You must call one of the SetMetainfo() functions before creating
874    a torrent with a tr_ctor.  The other functions are optional.
875
876    You can reuse a single tr_ctor to create a batch of torrents --
877    just call one of the SetMetainfo() functions between each
878    tr_torrentNew() call.
