--[[
  Main Neovim configuration. Aims to be mostly language agnostic. Code which is
  language specific and buffer-local was moved to corresponding ftplugins in
  the directory "ftplugin" instead. Also, larger chunks of coherent code were
  refactored into libraries in "lua" or plugins in "plugin" to not clutter the
  main configuration file.
