Minimal Configuration

-- Minimal configuration
-- mini.lua
-- Use with the --clean -u flags. EG nvim --clean -u mini.lua
-- This config will create a temp directory and will blow away that temp directory
-- everytime this configuration is loaded. Great for simulating a new installation
-- of a plugin
-- Setting some basic vim options
-- Some junk because I am sick of formatting tables in print

Screenshot

It seems as though the timer that is supposed to kick off and update "dynamically" created highlight groups is not working properly and thus sunglasses never has anything to do.
