#
# NOTES
# =======
# This implements a very basic method to retrieve all products
# from reqres.in and return them over an HTTP connection as
# a simple table. 
# Note this uses a web server suitable for DEBUGGING only. 
# Production use would see this replaced with a suitable 
# frontend mechaism.
