# 1. topsBatch.py takes .zip files in current directory and makes a director for each
# pair of images YYYYMMDD_YYYYMMDD, writes xml file for the corresponding pair
# and then runs topsApp.py in each directory.
# To avoid time-out, lauch tmux session before running topsBatch.py
# 2. TopsBatch requries writexml.py to be in same directory. Check writexml for dem and bounding box changes... (not in function yet)
