This is the first commit of the teaser example documented on www.github.com/ConnectedSets/ConnectedSets.  The exapmle's components are as follows:

- server.js that can be started as follows:  node server.js.  This server listens to port 8080 on the loopback interface.  It provides a dataflow from a json database file
- database.json that is the database file holding the data
- client.js that consumes server.js to request a sales dataflow provided dynamically by the server whenever an update occurs on database?json data
- index.html that uses cilent.js to display the sales dataflow in real time and without page refresh (in the browser) as database.json is changed with any of the 4 CRUD actions
