 The `elmMapbox` function accepts an options object that takes the following options:
 
  - `token`: the Mapbox token. If you don't pass it here, you will need to use the `token` Elm attribute.
- - `outgoingPort`: the name of the outgoing port. Default: `elmMapboxOutgoing`.
- - `incomingPort`: the name of the incoming port. Default `elmMapboxIncoming`.
- - `easingFunctions`: an object whose values are easing functions (i.e. they take a number between 0..1 and return a number between 0..1). You can refer to these with the `easing` option in the Cmd module.
+ - `easingFunctions`: an object whose values are easing functions (i.e. they take a number between 0..1 and return a number between 0..1). You can refer to these with the `easing` option in the Cmd.Option module.
+ - `onMount` a callback that gives you access to the mapbox instance whenever a map gets instantiated. Mostly useful for registering plugins.
