延遲載入

1. 如果延遲載入的依賴項需要其他延遲載入的依賴項，請確保以正確的順序載入它們！

angular.module('lazy', [
 'alreadyLoadedDependency1',
 'alreadyLoadedDependency2',
 ...
 {
  files: [
  'path/to/lazily/loaded/dependency1.js',
  'path/to/lazily/loaded/dependency2.js', //<--- requires lazily loaded dependency1
  'path/to/lazily/loaded/dependency.css'
  ],
  serie: true //Sequential load instead of parallel
 }
]);
