/** Definition:
 * This class allows deleting components (sensors, devices or markers) from the map layer
 * 
 * Command examples:
 * delete all
 * -> It deletes all objects (sensors, devices and markers) from the map layer
 * delete all sensors
 * -> It deletes all sensors (sensors, bas stations and media sensors) from the map layer
 * delete all events
 * -> It deletes all events (gases) from the map layer
 * delete all mobiles
 * -> It deletes all mobiles from the map layer
 * delete all markers
 * -> It deletes all markers from the map layer
 * delete all sensors mobiles
 * -> It deletes all defined objects (collection of objects) from the map layer
 * delete selected
 * -> It deletes all selected objects from the map layer
 * delete objects S1 S2 A3
 * -> It deletes all defined nodes (sensors and devices by their names) from the map layer
 * delete markers 0 1
 * -> It deletes all defined markers (by their indices) from the map layer
