Added male tail

Hi Raymond - didn't realize you were back. Took the liberty of proposing a new structure and arbitrarily grabbed IDs in the 001xxxxx. You know the anatomy way better than me, so you may want to reject this request and do it yourself from scratch.

If accepted, fixes issue #2

Added 2 NTs: male tail and male tail tip,
required for GO
