Change Splunk Version to 7.0

All this is a great deployment template! I have been looking through the code and for the life of me I can't figure out how to change what Splunk version gets installed or even where it is calling the Chef recipe to install Splunk Enterprise 6.6. Sorry for the noob question any help would be appreciated, I want to use this to deploy spunk 7.0

The issue does not name a template or file. Start by searching the repository for the Splunk Enterprise 6.6 reference and the Chef recipe that installs it, then trace how the deployment selects the version. Done means the relevant deployment template installs Splunk 7.0 and its version choice is clear.
