+Logging and debuging facility
+=============================
+
+Levels:
+    DEBUG       Detailed information, typically of interest only when diagnosing problems.
+    INFO        Confirmation that things are working as expected.
+    WARNING     An indication that something unexpected happened, or indicative of some problem in the
+                near future (e.g. ‘disk space low’). The software is still working as expected.
+    ERROR       Due to a more serious problem, the software has not been able to perform some function.
+    CRITICAL    A serious error, indicating that the program itself may be unable to continue running.
+
+There are three loggers: `console_only`, `file_only` and `both`.
+
+Use: `from debug import logger` to import this facility into whatever module you wish to log messages from.
+     Logging is thread-safe so you don't have to worry about locks, just import and log.
