#
# How to use in 3 easy steps
#
# 1. Download this file onto your computer
#
# 2. Position a camera where you want to render a
#    stereo image for and make sure it's your selected
#    camera
#
# 3. Then run script and wait for it to work
#    To run it go to Python -> Run Python Script
#    Then locate the file on your computer
