/**
 * CModule is the base class for module and application classes.
 *
 * CModule mainly manages application components and sub-modules.
 *
 * @property string $id The module ID.
 * @property string $basePath The root directory of the module. Defaults to the directory containing the module class.
 * @property CAttributeCollection $params The list of user-defined parameters.
 * @property string $modulePath The directory that contains the application modules. Defaults to the 'modules' subdirectory of {@link basePath}.
 * @property CModule $parentModule The parent module. Null if this module does not have a parent.
 * @property array $modules The configuration of the currently installed modules (module ID => configuration).
 * @property array $components The application components (indexed by their IDs).
 * @property array $import List of aliases to be imported.
 * @property array $aliases List of aliases to be defined. The array keys are root aliases,
 * while the array values are paths or aliases corresponding to the root aliases.
 * For example,
 * <pre>
 * array(
 *    'models'=>'application.models',              // an existing alias
 *    'extensions'=>'application.extensions',      // an existing alias
 *    'backend'=>dirname(__FILE__).'/../backend',  // a directory
 * )
 * </pre>.
