Overview
--------

The Care Messenger Platform provides a message delivery and acknowledgement mechanism for registered users.  These messages are consumed on a televison, via a connected set top box and responded to via remote control.  

A message set can consist of one or more messages, each with up to 5 possible responses.  Each message in a set can also have multiple attached images or videos.  This provides a large amount of flexibility to cover a variety of use cases, from simple reminder messages to complex questionnaires.
