* Describes a logger instance

* Based on PSR-3: http://www.php-fig.org/psr/psr-3/
*
* The message MUST be a string or object implementing __toString().
*
* The message MAY contain placeholders in the form: {foo} where foo
* will be replaced by the context data in key "foo".
*
* The context array can contain arbitrary data, the only assumption that
* can be made by implementors is that if an Exception instance is given
* to produce a stack trace, it MUST be in a key named "exception".
*
* See https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md
