title: Doctrine Migrations Namespace Error
body: <p>I am trying to setup doctrine migrations on top of silex framework. I installed it through composer.</p>
  
  <pre><code>"doctrine/dbal": "2.3.*",
  "doctrine/migrations": "dev-master",
  </code></pre>
  
  <p>My console file:</p>
  
  <pre><code>...
  $app['composer_loader']-&gt;add('Doctrine\DBAL\Migrations', __DIR__.'/../vendor/doctrine/migrations/lib/');
  
  $helperSet = new \Symfony\Component\Console\Helper\HelperSet(array(
      "db" =&gt; new \Doctrine\DBAL\Tools\Console\Helper\ConnectionHelper($app['db']),
      "dialog" =&gt; new \Symfony\Component\Console\Helper\DialogHelper(),
  ));
  $console-&gt;setHelperSet($helperSet);
  
  $console-&gt;addCommands(array(
      // Migrations Commands
      new \Doctrine\DBAL\Migrations\Tools\Console\Command\DiffCommand(),
      new \Doctrine\DBAL\Migrations\Tools\Console\Command\ExecuteCommand(),
      new \Doctrine\DBAL\Migrations\Tools\Console\Command\GenerateCommand(),
      new \Doctrine\DBAL\Migrations\Tools\Console\Command\MigrateCommand(),
      new \Doctrine\DBAL\Migrations\Tools\Console\Command\StatusCommand(),
      new \Doctrine\DBAL\Migrations\Tools\Console\Command\VersionCommand()
  ));
  
  $console-&gt;run();
  </code></pre>
  
  <p>However when I run migrations:status It outputs:</p>
  
  <pre><code>C:\htdocs\bitvenda\app&gt;php console.php migrations:status
  
    [Doctrine\DBAL\Migrations\MigrationException]
    Migrations namespace must be configured in order to use Doctrine migrations
    .
  </code></pre>
  
  <p>What I am doing wrong?</p>
