smtpmail.py

# this code is mostly stolen from http://pymotw.com/2/smtplib/#module-smtplib
# it can send emails through an SMTP server with TLS authentication
# we use this with an recipe on IFTTT.com to get live updates for longer running
# trainings and to transfer results to a personal Dropbox before automatically
# shutting down the EC2 instance. This way we don't have to keep connected to
# the instance all the time.
