Advanced SimpleX Chat bot example

In most cases a simple REPL bot is sufficient, but in cases you want to program more advanced communication scenarios you may take a more complex event-based approach, as in this example.

Event-based approach allows you:

decide whether to connect to a user or not depending on any factors, e.g. user display name.
disconnect from users who send too many messages or send messages that bot finds inappropriate.
react to message deletions and editing.
process reply messages differently, taking the original message into account.
process and send images and voice messages.
create groups of users, e.g. to connect 2 users.
etc.
