nvm plugin

This plugin adds autocompletions for nvm — a Node.js version manager.
It also automatically sources nvm, so you don't need to do it manually in your .zshrc.

To use it, add nvm to the plugins array of your zshrc file:

plugins=(... nvm)

Settings

If you installed nvm in a directory other than $HOME/.nvm, set and export NVM_DIR to be the directory
where you installed nvm.

These settings should go in your zshrc file, before Oh My Zsh is sourced:

• NVM_HOMEBREW: if you installed nvm via Homebrew, in a directory other than /usr/local/opt/nvm, you
  can set NVM_HOMEBREW to be the directory where you installed it.

• NVM_LAZY: if you want the plugin to defer the load of nvm to speed-up the start of your zsh session,
  set NVM_LAZY to 1. This will use the --no-use parameter when loading nvm, and will create a function
  for node, npm, yarn, and the command(s) specified by NVM_LAZY_CMD, so when you call either of them,
  nvm will load with nvm use default.

• NVM_LAZY_CMD: if you want additional command(s) to trigger lazy loading of nvm, set NVM_LAZY_CMD to
  the command or an array of the commands.

• NVM_AUTOLOAD: if NVM_AUTOLOAD is set to 1, the plugin will automatically load a node version when
  if finds a .nvmrc file in the current working directory indicating
  which node version to load.
