-Logging
--------
-
-PicoFeed log in memory the execution flow, if a feed doesn't work correctly it's easy to see what is wrong.
-
-### Reading messages
-
-```php
-use PicoFeed\Logging\Logger;
-
-// All messages are stored inside an Array
-print_r(Logger::getMessages());
-```
-
-You will got an output like that:
-
-```php
-Array
-(
-    [0] => Fetch URL: http://petitcodeur.fr/feed.xml
-    [1] => Etag:
-    [2] => Last-Modified:
