/*
  Dwitter backup scripts.

  Is the API up?

  Yes: 1. Paste Script A into a Node console.
       2. Copy and save the output.

  No:  1. Go to https://www.dwitter.net/u/rileyjshaw.
       2. Scroll to the bottom so that all dweets are loaded.
       3. Paste Script B into a JS console.
       4. Copy and save the output.
