Currently configuration is shared between Vim and NeoVim, although I use NeoVim. Migration will happen when NeoVim 0.5.0 is released and `init.lua` is supported.
Configuration is separated into directories:
-`plugin` for logical collection of functionalities into a simple plugin
-`colors` my colorscheme
-`compiler` for compiler plugins
-`ftdetect` for autocommands for detecting file types
-`undodir` is just a placeholder for configured undo directory
-`spell` for spelling dictionary
-`after` with same directory structure for loading after plugins - allows easy overrides, most `ftplugins` are here
