This component encapsulates all the complex operations behind instantiating every component
needed and integrating it with the rest to allow the MVC pattern to operate as desired.

```php
<?php

use Phalcon\Mvc\Application;

class MyApp extends Application
{
/**
 * Register the services here to make them general or register
 * in the ModuleDefinition to make them module-specific
 */
protected function registerServices()
{

}

/**
 * This method registers all the modules in the application
 */
public function main()
{
    $this->registerModules(
        [
            "frontend" => [
                "className" => "Multiple\Frontend\Module",
                "path"      => "../apps/frontend/Module.php",
            ],
            "backend" => [
                "className" => "Multiple\Backend\Module",
                "path"      => "../apps/backend/Module.php",
            ],
