Dining Philosophers (C++17, Monitor Solution)

This project implements the classic Dining Philosophers concurrency problem using:

• std::thread for philosopher threads,
• a monitor-style synchronization class (Monitor),
• std::mutex + std::condition_variable for safe coordination.

The simulation runs continuously and prints philosopher states (THINKING, HUNGRY, EATING) in the terminal; stop with Ctrl+C. ANSI color escape codes are used in terminal output.

How it works

Each philosopher runs in its own thread and repeats this cycle:

1. Think
2. Ask monitor to pick up forks (PickUp)
3. Eat
4. Put down forks (PutDown)

The monitor ensures that adjacent philosophers cannot eat at the same time, but strict fairness is not explicitly enforced. When a philosopher becomes hungry, it waits on its own condition variable until both neighbors are not eating.
