How to override a class?

Live Helper Chat allows you to override default system classes. To override a class, the workflow should be as follows:

• Create an extension. See the extension example here.
• Copy the desired class from the kernel to the extension's class folder.
• Define the class path in var/autoloads/lhextension_autoload.php.
• 'class_name' => 'extension/..../myclass.php'

Now you are ready to go.
