Plugin API

Developers can easily log their own things using a simple API:

// Add events to the log
SimpleLogger()->info("This is a message sent to the log");

// Add events of different severity
SimpleLogger()->info("User admin edited page 'About our company'");
SimpleLogger()->warning("User 'Jessie' deleted user 'Kim'");
SimpleLogger()->debug("Ok, cron job is running!");
