Phantom Quelling

I thought that allowing the elevator a period of unchecked dynamics was allowing it to sort out the forces on the ribbon. It turns out that it was allowing the double precision floating point numbers overflow, and become NaN (not a number) in Java.

I need to review the equations again, to figure out what I introduced into the model when I converted it to Java. One of the changes was to use the vecmath library, where I may have swapped some of the parameters when I converted to the new routines. Again, I need to walk the code to determine if this is the cause of an issue.
