slog

A super simple go logger

I know there are many go loggers out there that offer various logging features such as file rotation, granular verbosity settings, colored and JSON output, etc.

Slog is not one of them.

Slog lets you hide or show debug logs as well as provides a simpler way to log messages with Warning and Error prefixes for consistency.

Also provided are a few simple methods for handling returned error variables, logging them out and optionally panicing or fatally exiting.
