\Psr\LogNullLogger

This Logger can be used to avoid conditional log calls.

Logging should always be optional, and if no logger is provided to your library creating a NullLogger instance to have something to throw logs at is a good way to avoid littering your code with if ($this->logger) { } blocks.
