A script to clone recently used github repos

${BASH_SOURCE[0]} is a script to clone recently used github repos. Potentially
useful when you have a new laptop.

Usage: ${BASH_SOURCE[0]} user token [clone_dir] [months]

  user: your github username
  token: a github token with enough permission to see the repos you want 
         to checkout (the repo scope seems to be required for private repos)
  clone_dir: the directory that repos should be cloned in (defaults to ~/code)
  months: the number of months to look back (defaults to 12)

When cloning this script uses ssh, please ensure you have already used ssh-add 
or similar to ensure your github ssh key is available.
