/**
 * This class requires the following parameters
 * <ul>
 * <li>templateDir: The directory where Smarty templates are located.</li>
 * <li>compileDir: The directory where Smarty templates are compiled.</li>
 * <li>configDir: The directory where configuration files are located.</li>
 * <li>cacheDir: The directory where the cache should be located.</li>
 * </ul>
 * <p>Optionally you can pass in these parameters as well:
 * <ul>
 * <li>caching: Should Smarty cache templates.  Defaults to false.</li>

 * <p>You can also pass in anything else to this class and the plugin will
 * do an initial assign for the key to the value.  So you could pass in
 * appName=MyApp and this plugin would assign the appName key to MyApp
