I provide these Mathematica documents to use and share as you see fit.  If you use them in any kind of academic pursuit I would appreciate some small acknowledgment and would just be interested in general to know if they were at all useful to you.  However, I have not "stress tested" these files as I polished them to my own needs and called it quits.  I tend to use Mathematica to perform calculations whose computational complexity increases greatly with the input parameters.  Therefore, I am not responsible for frozen computers, lost data, etc... as a result of using these files.  USE AT YOUR OWN RISK!
