Email notification of your finished program or due to interruptions. Sends Runtime information and screen output.

# ---------------------------------------------------------------------
# This script measures the runtime of your post-processing program
# and sends an email notification with the information:
# - Start time
# - End time
# - Runtime
# - Your program screen output or interruptions.
