/**
 * TJsonService class provides to end-users javascript content response in
 * JSON format.
 *
 * TJsonService manages a set of {@link TJsonResponse}, each
 * representing specific response with javascript content.
 * The service parameter, referring to the ID of the service, specifies
 * which javascript content to be provided to end-users.
 *
 * To use TJsonService, configure it in application configuration as follows,
 * <code>
 *  <service id="json" class="Prado\Web\Services\TJsonService">
 *    <json id="get_article" class="Path\To\JsonResponseClass1" .../>
 *    <json id="register_rating" class="Path\To\JsonResponseClass2" .../>
 *  </service>
 * </code>
 * where each JSON response is specified via a &lt;json&gt; element.
 * Initial property values can be configured in a &lt;json&gt; element.
 *
 *
 * PHP configuration style:
 * <code>
 *  'services' => array(
 *    'get_article' => array(
 *     'class' => 'Path\To\JsonResponseClass1',
 *     'properties' => array(
 *       ...
 *	    )
 *    )
 *  )
 * </code>
 *
 * To retrieve the JSON content provided by "get_article", use the URL
 * <code>index.php?json=get_article</code>
