'''
Sends one email with attachment to each student on a list

Prepare a data file (plain text) with the format:
file1, email1, text1
file2, email2, text2
file3, email3, text3
...

Overwrite the configuration vars below and run this script.
email1 will receive an email with file1 attached, and text1
will replace the format chars %s inside the generic body text
(see example below).
