* This program is a simple federated chat application written in Lingua Franca | ||
* (LF) for two users, represented by two instances of the `ChatHandler` | ||
* reactor, `a` and `b`. Each `ChatHandler` consists of an `InputHandler` and a | ||
* `Printer`. The `InputHandler` is responsible for receiving user input from | ||
* the console and sending it as a message. When the user enters a message, the | ||
* `InputHandler` reads it, prints it, and then sends it via its `out` port. The | ||
* message then gets relayed by the `ChatHandler` via its `send` port. On the | ||
* receiving side, the `ChatHandler` directs the incoming message through its | ||
* `receive` port to the `Printer` reactor, which prints the received message. | ||
