### Drawing
A single right click will allow you to add a point to the map - you must specify the `name` and optionally the `icon` and `layer`.
Right-clicking on an icon will allow you to delete it.
If you select the **drawing** layer you can also add polylines, polygons and rectangles.
All these events generate messages that can be received by using a **websocket in** node set to the same endpoint. For example:

del:joe

### Control
You can also control the map via the websocket, by sending in a msg.payload containing a **command** object.
