+Wa72SimpleLogger
+================
+
+Wa72SimpleLogger is a very, very simple file logger implementing \Psr\Log\LoggerInterface (PSR-3)
+
+Wa72SimpleLogger is intended for small projects without a framework,
+or if your framework does not support PSR-3 yet, and you don't want to use more
+sophisticated logging solutions like Monolog. If you just need to output a few log
+messages to a log file but want to stick to the PSR-3 standard (thus having the option to upgrade
+to another logger) this class is for you.
