auto-label-images.py

# This script is for automatically labeling all the images in a directory with their
# names (for lab reports, technical documents etc.). Uses ImageMagick's convert command.
# Currently windows specific, but it should be easy to make compatible with linux

# This may also be possible as a one-liner with image magick.
