Added python_logger presentation from Oct 2014
simplified Pledge enrollment instructions

This is a first-pass at the documentation for simplifying the Pledge enrollment process of creating a profile, downloading and installing the software, downloading and activating the Pledge profile, and using the software to log into the system.

Further refinements are necessary, including adding some updated screenshots and/or screencap video.
Added presentation and example script. Also added __init__.py to Andy's folder
from last week to make his code importable.
Moved example into notebook at end.
Merge pull request #15 from aculich/patch-2
