// Bollinger Bands via the generalised `moving_constant_bands`.
//
// Bollinger Bands are the special case of `moving_constant_bands` that uses
// the simple moving average as the centre line and the standard deviation as
// the dispersion measure. Swap either model to roll your own variant.
//
// Run with:
//   cargo run --example bollinger
