// Stopwatch support for spdlog  (using std::chrono::steady_clock).
// Displays elapsed seconds since construction as double.
//
// Usage:
//
// spdlog::stopwatch sw;
// ...
// spdlog::debug("Elapsed: {} seconds", sw);    =>  "Elapsed 0.005116733 seconds"
// spdlog::info("Elapsed: {:.6} seconds", sw);  =>  "Elapsed 0.005163 seconds"
//
//
// If other units are needed (e.g. millis instead of double), include "fmt/chrono.h" and use
// "duration_cast<..>(sw.elapsed())":
//
// #include <spdlog/fmt/chrono.h>
//..
// using std::chrono::duration_cast;
// using std::chrono::milliseconds;
// spdlog::info("Elapsed {}", duration_cast<milliseconds>(sw.elapsed())); => "Elapsed 5ms"
