The events global, `ModAPI.events`, allows you to register new event types and call them.
#### ModAPI.events.newEvent(eventName: String)
You can register new events using ModAPI, as long as the event name starts with `custom:`. For example, if I want to add a new event that can be used by other mods, I can use `ModAPI.events.newEvent("custom:myevent")`.
You can register new events using ModAPI, as long as the event name starts with `custom:` (`lib:` is only useful for library loading). For example, if I want to add a new event that can be used by other mods, I can use `ModAPI.events.newEvent("custom:myevent")`.

#### Using library load events
```javascript
// Mod #2, registers and calls lib event
ModAPI.events.newEvent("lib:mylibrary:loaded");
ModAPI.events.callEvent("lib:mylibrary:loaded", {});
```
```javascript
// Mod #1, registers event handler for lib event
ModAPI.addEventListener("lib:mylibrary:loaded", (e)=>{
//Lib events function differently to normal events, as when they are called once, any new event listener with automatically fire upon being registered.
