 Simple logger I wrote to have a unified system for logging throughout my projects.

+- Automatic file rotation, currently only rotates files on startup
 - Discord webhook, need to write a separate package for that, don't want to add the entirety of d.js as a dep just for a webhook

-    guard: '_logger', // Message guard, e.g this property has to be true in the IPC message for the logger to read it
-    debug: false, // On the master logger this determines whether the output is written to console (i.e. will always be written to file), on the client this determines whether it is sent to the master at all
     customTypes: [], // Log types, defaults are 'error', 'warn', 'info', 'debug', 'status'. Each one of these has an associated shorthand function, the custom ones will receive one too, e.g. adding 'access' to the custom types will add a logger.access() function
-    /////// MASTER EXCLUSIVE
     customStreams: [], // File streams, by default there are streams for error and default
     customTypeMapping: {}, // This maps a type to a stream, e.g. adding "warn": "error" will pipe any warnings to the error log file
     customColors: {}, // Supports any colours chalk.js supports, e.g. "warn": "green" will turn warning outputs green
-    fileRotationFreq: 1, // How frequently to roate files in days - will not work with anything less than 1 day currently
+    debug: false
