Sector Timing Example for DovesLapTimer

This example demonstrates 3-sector split timing using a SYNTHETIC GPS track — no GPS hardware required. The library is driven through three simulated laps around a 100m × 100m square loop so you can see sector times, best times, and optimal-lap calculation light up on Serial.

Sector layout:

• Sector 1: Start/Finish -> Sector 2 line
• Sector 2: Sector 2 line -> Sector 3 line
• Sector 3: Sector 3 line -> Start/Finish

To adapt for a real track:

1. Replace the four pairs of crossing-line coordinates below with your own (Google Maps right-click -> copy lat,lng).
2. Delete generateSyntheticFix() and the LAPS_TO_RUN stop condition.
3. In loop(), replace the synthetic GPS block with reads from your GPS module: feed lat, lng, altitude (m), and speed (knots) into lapTimer.loop(), and ms-since-midnight into lapTimer.updateCurrentTime().

const double TRACK_WEST_LNG = -81.37970
