• Open a socket connections to APNs or Feedback servers.
• Make an alert dictionary to send in the payload.
• Make a notification including payload JSON and turn into C struct.
• Send notification as C struct via socket to APNs.
• Connect to the Feedback server with a socket (receiving data not yet implemented).
