Persistant backbone storage through dnode pub/sub

// ------

// Main application

})

// Start up the application and connect to the mongo 
// database if not part of another module or clustered, 
// configure the Mongoose model schemas, setting them to 
// our database instance. The DNode middleware will need 
// to be configured with the database references.

// Initialize
// ----------

// Start up the server

// General error handling
