# Polls the ESP8266 sensor continuously for door contact status.
# This script provides an example of pull data using HTML calls.  The
# pull is using a REST-like method, but not truly REST (because the web
# ESP8266 does not implement full REST.  The script then parses the response 
# for the appropriate date (in case the status of the sensor).  Then the 
# script pushes the data to the server using a RESTful call (in this case the
# server does support REST).  This process is repeats over and over unless
# there is an issue with the ESP8266.
