 ** Description
 
 This script prints out a more useful traceback when you make script calls.
 Rather than some arbitrary message thrown by the interpreter that something
 went wrong somewhere, you can see exactly why an error occurred. The script
 editor also automatically moves to the line in question.

 ** Required
 
 Full Error Backtrace
 (http://himeworks.wordpress.com/2013/06/09/custom-main-full-error-backtrace/)
 
--------------------------------------------------------------------------------
 ** Installation
 
 Place this script below Materials and above Main
 
--------------------------------------------------------------------------------
 ** Usage

 Plug and play.
 Traceback is printed to the console

  # Just based on observed behavior. Script calls only have one argument
  # to eval by default so this should be fine until someone finds a reason to
  # pass in more arguments?
