title: Creating package on Packagist and the package installation path
body: <p>I have created a <a href="/questions/tagged/yii2" class="post-tag" title="show questions tagged 'yii2'" rel="tag">yii2</a> extension. It is a Yii2 widget. I created a <a href="https://github.com/saidbakr/yii-jui-themes-list" rel="nofollow">GitHub repository for it</a>. After some issues with <code>composer.json</code> I have, successfully, to this <a href="https://packagist.org/packages/saidbakr/yii-jui-themes-list" rel="nofollow">Packagist package</a>.</p>
  
  <p>Now I could able to install it using composer in any yii2 appliaction using the following command:</p>
  
  <pre><code>composer require saidbakr/yii-jui-themes-list=1.2
  </code></pre>
  
  <p>There is a problem: it has been installed under <code>vendor\saidbakr\yii-jui-themes-list</code> However, I want it to be installed directly on <code>vendor\saidbakr</code> because of my PHP code namespace considering this namespace. So is there any way that gives me a control to where the package should be installed or at least to make my files to be placed on the repository owner directly?</p>
