+The logs module exposes various log types that can be used to indicate logs.
+This helps users filter for the logs that they care about.
+
+The logs are encoded as strings as to allow the addition of new log types
+without triggering a major update.

+This module extends the standard JSON encode / decode library for security
+measures. Most Elm libraries do not access an API this often without insight
+for the user, and hence this module aims to offer the user more insight into
+what is going on.
+
+Additionally, the decoder will warn for suspicious values, and provide helpful
+errors when the JSON fails to decode.
