Log to console each transition change (useful to intercept a state before it change)

rootscopeListener.js

angular.module('SkylineApp').run(function($rootScope) {
  return $rootScope.$on("$stateChangeStart", function(evt, toState, toParams, fromState, fromParams) {
    return console.log("Transitioning from: " + fromState.name + " to: " + toState.name);
  });
});
