 --angular_pass                         : Generate $inject properties for
                                          AngularJS for functions annotated
                                          with @ngInject
 --assume_function_wrapper              : Enable additional optimizations based
                                          on the assumption that the output
                                          will be wrapped with a function
                                          wrapper.  This flag is used to
                                          indicate that "global" declarations
                                          will not actually be global but
                                          instead isolated to the compilation
