2.0 CHANGES:
* Detects intercepted probes and marks avoids. Allows the user to
* begin probing from a specified line in the target list and reports
* "restart line" when interrupted. The API does not detect when a
* probe is destroyed at its destination, so keep your eyes on the
* screen! [Note: LaunchEtherProbe.exec() hangs when a probe is
* destroyed, so this script is effectively broken.]
*
*
1.1 CHANGES:
* Remembers target list filename between runs. Fixed a minor bug
* which may not have ever existed.
