	/**
	 * Imports a class or a directory.
	 *
	 * Importing a class is like including the corresponding class file.
	 * The main difference is that importing a class is much lighter because it only
	 * includes the class file when the class is referenced the first time.
	 *
	 * Importing a directory is equivalent to adding a directory into the PHP include path.
	 * If multiple directories are imported, the directories imported later will take
	 * precedence in class file searching (i.e., they are added to the front of the PHP include path).
	 *
	 * Path aliases are used to import a class or directory. For example,
	 * <ul>
	 *   <li><code>application.components.GoogleMap</code>: import the <code>GoogleMap</code> class.</li>
	 *   <li><code>application.components.*</code>: import the <code>components</code> directory.</li>
	 * </ul>
	 *
	 * The same path alias can be imported multiple times, but only the first time is effective.
	 * Importing a directory does not import any of its subdirectories.
	 *
	 * Starting from version 1.1.5, this method can also be used to import a class in namespace format
	 * (available for PHP 5.3 or above only). It is similar to importing a class in path alias format,
	 * except that the dot separator is replaced by the backslash separator. For example, importing
	 * <code>application\components\GoogleMap</code> is similar to importing <code>application.components.GoogleMap</code>.
	 * The difference is that the former class is using qualified name, while the latter unqualified.
	 *
	 * Note, importing a class in namespace format requires that the namespace is corresponding to
	 * a valid path alias if we replace the backslash characters with dot characters.
	 * For example, the namespace <code>application\components</code> must correspond to a valid
	 * path alias <code>application.components</code>.
	 *
	 * @param string $alias path alias to be imported
	 * @param boolean $forceInclude whether to include the class file immediately. If false, the class file
	 * will be included only when the class is being used. This parameter is used only when
	 * the path alias refers to a class.
	 * @return string the class name or the directory that this alias refers to
	 * @throws CException if the alias is invalid
