var originalModule = angular.module;

    var mod = originalModule.apply(angular, arguments);
    var injector = angular.injector(modules ? ['ng'].concat(modules) : ['ng']);

// Usage
var myApp = angular.module('myApp',[])
    .controller('BaseCtrl', function() {
        this.a = function() {};
    })
    .inheritController('ExtendedCtrl', 'BaseCtrl', function() {
        this.a(); 
    })
