//------------------------------------------------------------
// A refueling center is one segment... to identify it in the
// segment structure, the "special" field is set to 
// SEGMENT_IS_FUELCEN.  The "value" field is then used for how
// much fuel the center has left, with a maximum value of 100.

//-------------------------------------------------------------
// To hook into Inferno:
// * When all segents are deleted or before a new mine is created
//   or loaded, call fuelcen_reset().
// * Add call to fuelcen_create(segment * segp) to make a segment
//   which isn't a fuel center be a fuel center.  
// * When a mine is loaded call fuelcen_activate(segp) with each 
//   new segment as it loads. Always do this.
// * When a segment is deleted, always call fuelcen_delete(segp).
// * Call fuelcen_replentish_all() to fill 'em all up, like when
//   a new game is started.
// * When an object that needs to be refueled is in a segment, call
//   fuelcen_give_fuel(segp) to get fuel. (Call once for any refueling
//   object once per frame with the object's current segment.) This
//   will return a value between 0 and 100 that tells how much fuel
//   he got.
