Created a "Fly to" panel to allow the user to enter a position and fly to that position.
Created an interface to interpret positions specified in different ways and a first implementation that interprets space separated Lat Lon coordinates.
The panel also maintains a current location and two sets of previous and next locations with two button to move between them.
