Events
The map has several events. You can trigger actions to happen when these events occur.

This event happens when the Map has loaded in your app. 
This is a good time to add any markers, polylines or polygons to your app that you want the user to see as soon as your app opens.
On User Location Change
This event happens when the location of the user changes. It returns the coordinate object.
You can use object blocks to get the properties of the coordinate object.
The coordinate object has the following properties:
{
    target: Numeric ID for your app
    coordinate:{
          latitude: latitude of point selected
          longitude: longitude of point selected 
    }
    position:{
          x: x-position of selected point on the Map component
          y: x-position of selected point on the Map component
    }
}
On Press
This event happens when the user taps on the Map.
