// the key figures of a vehicle's run, for each part of it between two events of the test: the speeds, the
// distance, the time to stop, the brake pipe's lowest pressure and the time it took to get back, the brake
// cylinders', the motor current's and the tractive force's peaks. a golden trace keeps them next to its
// samples, in data/golden/<Name>.figures, which a person reads:
//
//   [emergency]
//   duration = 40.00 s
//   speed at the start = 80.0 km/h
//   speed at the end = 0.0 km/h
//   distance = 412.3 m
//   stopped after = 38.21 s
//   brake cylinders peak = 3.800 bar
//
// a figure the vehicle doesn't have (no speed, no current) is left out of all the parts. they're compared
// within 0.5%, loose enough for any compiler, so a change which alters the behaviour on purpose shows in their
// diff in a few readable lines, where the samples change in thousands
