 * A factory for creating local commands. It's useful in cases where
 * instantiation of a command is more complicated than just using the default
 * constructor. For example, when arguments must be passed into the constructor
 * or when using a dependency injection framework. When a LocalCommandFactory
 * isn't used, you can provide the AdHocCommandManager a Class object instead.
 * For more details, see
 * {@link AdHocCommandManager#registerCommand(String, String, LocalCommandFactory)}
