[IDV #ABK-864576]: Trajectory Bug

Jim,
      I did see a bug in the calculation of backward trajectory, and checked in 
a fix. You can try the nightly in 20 minutes, which is 5.0u1 release.

      I can not find the dataset you were using, I used the NAM80km, see the 
attached image. I will do some comparison with gempak next week.
