// class for balloon manipulation using simulated auto pilot
// written: 8/29/93  (based on an idea of Dave Reed)
// modified: 8/30/94, 12/29/94

// member function explanation:
//
// Ascend: balloon ascends to height specified by parameter
//         in a sequence of burns.  Each burn raises the
//         altitude by 10 meters
//
// Cruise: balloon cruises at current altitude for a number of time
//         steps specified by parameter.  Random wind-shear can cause
//         balloon to rise and fall, but vents and burns keep the
//         balloon within +/- 5 meters of the altitude at which cruising
//         starts

// Descend:   balloon descends to height specified by parameter in a
//            sequence of vents.  Each vent drops the balloon 10 meters,
//            or to the ground (if less than 10 meters to the ground)
