The main application interface into timber.
This class gives you a way to create Logger classes.
This is a convenient way to expose a log member to classes that need to log and pull in the implicits that are needed for normal logging patterns.
Message represents the textual content of the log entry.
This trait has no significance other than marking classes that can be used as tags in timber.
Message contains some "static" functions that are useful to consumers of the API.
