/**
 * USAGE
 * 
 * First copy the script and paste it in Chrome DevTools in Sources -> left pane -> Snippets.
 * Then, after loading an Angular page, right click on the snippet and choose "run".
 * Afterwards, you have the following available in the console:
 * 
 * 1) $rootScope
 * 2) inject(function ($q, $compile) { ...use $q and $compile here... });
 * 3) click on an element in DevTools; now $scope in the console points at the element scope (isolate if one exists).
 * 
 * Enjoy!
