//This class provides a text interface for controlling VR-Forces over the network.
//This interface currently supports the following actions:
//
//1. load <filename> 
//     load a scenario file

//2. save <filename>
//     save the current scenario

//3. new <db filename>
//     create a new scenario

//4. close
//     close the current scenario

//5. rewind
//     rewind the current scenario to its start state

//6. run
//     sends a message interface request to run the current scenario

//6a. simrun
//     sends a sim mgmt start PDU to run the current scenario

//7. simpause
//     sends a sim mgmt stop PDU to pause the current scenario

//7a. pause
//     sends a sim mgmt pause request to pause the current scenario

//8. list
//     list all the backends that are currently running

//9. create [ waypoint | route | tank | aggregate]
//     create a VR-Forces waypoint, route, tank, or tank aggregate

//10. delete [ <object_name> | <object_id> ]
//     delete a VR-Forces object by name or by object ID

//11. set [ plan | label | location | fuel | target | restore ]
//     set a VR-Forces object attribute

//12. task [ patrolRoute | moveToPoint | follow | wait ]
//     task a VR-Forces entity

//13. aggregate "name1" "name2" "name3"
//     aggregate 3 VR-Forces entities together

//14. timemultiplier
//     sets the time multiplier on the exercise clock

//15. quit
//     quit the application
