# Description: This file demonstrates the use of linked Azure Resource Manager (ARM) templates and techniques such 
# as passing objects into and out of the various linked templates. It also demonstrates using parameters, variables, 
# and objects to take a "generalized" input parameter (say: small, medium, large) and "explode" that into multiple 
# detailed settings
#
# For more about these techniques, see: https://brentdacodemonkey.wordpress.com/2017/03/09/azure-resource-manager-template-tips-and-tricks/
