 #### Non-standard events:
 **auto** - for example, you need to click on the same button on the second step imediatelly after the first step and go to the next step after it. Then you can use "auto" in the "event_type" property and "click" in "event" property.
 * `custom` - this value is very usefull if you need to go to the next step by event in your app code. For example, you want to go to the next step only after some data have been loaded in your application. Then you should use the "custom" event_type and the "trigger" method of the EnjoyHint instance.
