Detailed Description

A sequential chain of timed events with precise temporal control.

The EventChain class provides a way to schedule a sequence of events to occur at specific time intervals. It's designed for creating temporal sequences of actions with sample-accurate timing, which is essential for deterministic computational flows.

This approach is inspired by reactive programming and temporal logic systems where precise sequencing of operations is critical. It allows for creating complex temporal behaviors with a simple, declarative API.

Example usage:

// Create an event chain
EventChain chain(*scheduler);
 
// Add events with specific delays
chain.then([]() { process_initial_state(); })      // Immediate
     .then([]() { transform_data(); }, 0.5)        // After 0.5 seconds
     .then([]() { apply_filter(); }, 0.25)         // After another 0.25 seconds
     .then([]() { finalize_output(); }, 0.25);     // After another 0.25 seconds
 
// Start the chain
chain.start();

The EventChain is particularly useful for creating precisely timed computational sequences, state transitions, or any series of time-based events that need to occur in a specific order with deterministic timing.
