+// Thread safe logger (except for set_pattern(..), set_formatter(..) and set_error_handler())
+// Has name, log level, vector of std::shared sink pointers and formatter
+// Upon each log write the logger:
+// 1. Checks if its log level is enough to log the message
+// 2. Format the message using the formatter function
+// 3. Pass the formatted message to its sinks to performa the actual logging
