+  These cellular modules use TTL Serial to communicate, 2 pins are
+  required to interface

+THIS CODE IS STILL IN PROGRESS!
+Open up the serial console on the Arduino at 115200 baud to interact with FONA
+This code will receive an SMS, identify the sender's phone number, and automatically send a response
