3D Map updates

[Andrew J. Hoag]

I have added ERA, NETGOD, IBM and verified that the map is current with the
RIPE database (as of 0800 PST). Sometime this weekend I'll try and produce the
seperations for the T-shirt for Bob. If there are any last minute tunnel
changes, let me know before Sunday.

I'm going to start publishing the tunnels that I've found to be asymmetric. In
munging the data I can produce some stats... This most current run is shown
below:

121 (63 / 58 dups) tunnels processed for 43 sites.
Asymmetric tunnel: ERA (192.71.20.139) --> SICS (193.10.66.50)
Asymmetric tunnel: ERA (192.71.20.139) --> G6 (129.88.26.1)
Asymmetric tunnel: NETGOD (206.129.65.250) --> WWU (140.160.166.22)
Asymmetric tunnel: NRL (132.250.90.5) --> IFB (194.105.166.254)
Asymmetric tunnel: TELEBIT (194.182.135.253) --> G6 (193.55.240.18)

Meaning my program found 43 RIPE-NCC files (I removed NUS since it duplicated
NUS-IRDU) with 121 tunnels. Of those, 63 were original and 58 were the
reverse-direction. Five tunnels (listed above) do not have both directions
defined in both files.
