Fixed the script so it won't crash anymore. Sorry for delaying so long on this!

I know this script has been done over and over, however I don't like the execution of the others. I decided to write this from scratch today because I was looking for a tad bit more functionality. If you ever used a script called Zoomerator this is a bit like that, in some cases but with a bit more love :)

This script invaluable to camera tracking and modeling, let alone control of simple keyframing of the camera attributes. If this is proven useful, I would like to push it even further to encompass translating/rotating/aiming as well as possible DOF solutions.

Email me if you have suggestions or comments for this script!
