 * * I init the necessary modules
 * * I load the project index data from the server
 * * I ensure the user is logged
 * * I prepare the interface
 *
 * I am a "one-pass" module, this is: I don't export any public methods or properties, and 
 * my sole purpose is to start other modules, after which I am discarded.
