Also, we need to solve the following issues with auto command flight analysis:
Using SITL I have found further errors

• At the end of the flight we get "End of Saved AUTO Commands List"
• During the new mission at the top of the log command 0 should contain the current position of the Copter, so if there are 4 lines in the mission log there will be 5 lines in the new mission. Can we use this to set the starting position. What happens if GPS has not got a position?
• Because of the above alter the count from 1 to 4, ignoring zero.
• During the mission if Lon or Lng is zero the set the starting position to GPS, if that does have some good co-ordinates.
