Raspberry Pi zero SMS relay

#!/usr/bin/env python
#starter.py - a quick and dirty remote start via SMS project
#came about when I was driving a work truck to my personal truck located at the shop I work in
#the thermometer in the work truck told me it was 17 degrees. I wished there was a way to start my personal
#from wherever I am instead of the limited range of the keyfob I have to remote start it normally.
#add 
#    "sudo python /home/pi/starter.py &"
#to the file "/etc/rc.local" before the end where it says
#   exit 0
#The personal has an Avitol 4103 remote start installed, with an activation pin.
#all the wiring I am going to do is tied in to the wiring for the remote start.
#First ever python project.
