Struct TemaEngine 

pub struct TemaEngine { /* private fields */ }

Triple Exponential Moving Average (TEMA) over the closing price.

TEMA = 3 * e1 - 3 * e2 + e3 over three chained exponential averages of period — e1 over the close, e2 over e1, e3 over e2 — each the shared Ema with its first-sample seed. All three run from the first close; only the output is withheld until the period-th bar.

That chaining differs from super::moving_averages::DemaEngine, whose second stage starts with the first published value of the first. The two produce different early values and converge as the seeds decay.

First output: with the period-th bar. Indicator::reset clears all three averages.
