Handles SMS to XMPP and XMPP to SMS communications
WARNING: USE AT YOUR OWN RISK.
Take in SMS from Twilio as an HTTP GET and pipe it to XMPP, and vice versa.
Create a creds.py file with: server = "your.xmpp.server" domain = "your.xmpp.domain" user = "yourXmppUser" password = "yourXmppPassword"
Point your Twilio SMS endpoint to your server at port 14444 using GET requests.
Run gateway.py.
