+#### To add a minimap
+
+A minimap overview can be added by sending a suitable command. The "minimap" property
+must specify the name of an existing base layer to use. The "opt" property can contain 
+valid options from the [minimap library options](https://github.com/Norkart/Leaflet-MiniMap#available-options).

+    			toggleDisplay: true
