run.js versus main module

run-module.js

 * The bootstrap for the app is a module.  The weird thing about this option 
 * is that it uses curl(), rather than require(), inside the module to load
 * other modules, such as the app's main module.  
 * The script element to execute this bootstrap would look like this:
 *
 *   <script data-main="client/run-module" src="client/lib/curl.js"></script>
