Presage python demo
-----------------------
This program is intended as a demonstration of Presage ONLY.
The Presage project aims to provide an intelligent predictive text
entry platform.
Its intent is NOT to provide a predictive text entry user interface.
Think of Presage as the predictive backend that sits behind a shiny
user interface and does all the predictive heavy lifting.
