* Register a component definition with the compiler. This is short for registering a specific
* subset of directives which represents actual UI components in your application. Component
* definitions are very simple and do not require the complexity behind defining directives.
* Component definitions usually consist only of the template and the controller backing it.
* In order to make the definition easier, components enforce best practices like controllerAs
* and default behaviors like scope isolation, restrict to elements.
*
* <br />
* Here are a few examples of how you would usually define components:
*
* ```js
* var myMod = angular.module(...);
* myMod.component('myComp', {
* template: '<div>My name is {{myComp.name}}</div>',
* controller: function() {
* this.name = 'shahar';
* }
* });
*
* myMod.component('myComp', {
* template: '<div>My name is {{myComp.name}}</div>',
* bindings: {name: '@'}
* });
*
* myMod.component('myComp', {
* templateUrl: 'views/my-comp.html',
* controller: 'MyCtrl as ctrl',
* bindings: {name: '@'}
* });
*
* ```
*
* <br />
* Components are also useful as route templates (e.g. when using
* {@link ngRoute ngRoute}):
*
* ```js
* var myMod = angular.module('myMod', ['ngRoute']);
*
* myMod.component('home', {
* template: '<h1>Home</h1><p>Hello, {{ home.user.name }} !</p>',
* controller: function() {
* this.user = {name: 'world'};
* }
* });
*
* myMod.config(function($routeProvider) {
* $routeProvider.when('/', {
* template: '<home></home>'
* });
* });
* ```
*
* <br />
* When using {@link ngRoute.$routeProvider $routeProvider}, you can often avoid some
* boilerplate, by assigning the resolved dependencies directly on the route scope:
*
* ```js
* var myMod = angular.module('myMod', ['ngRoute']);
*
* myMod.component('home', {
* template: '<h1>Home</h1><p>Hello, {{ home.user.name }} !</p>',
* bindings: {user: '='}
* });
*
* myMod.config(function($routeProvider) {
* $routeProvider.when('/', {

* resolve: {user: function($http) { return $http.get('...'); }}

Better to use isArray() now that we're here.

Minor, but options.transclude or options.transclude || false would work as well (now that false is the default).
