# React to ear movement program
# Put in task scheduler, checks every 5 minutes

# Edited 12/2: corrected error: close bunnyFile after done
#              changed pickling to use ascii files, rather than binary
#              removed error handling upon opening pickle file
#              added print statements to help debug.
