@davfaulk did you want to fix this?

Sorry for the delayed response on this. We have since removed the redundant docs/policy_templates_data/policy_templates.json file so now the only file to modify is samtranslator/policy_templates_data/policy_templates.json Can you merge the latest develop branch, resolve conflicts and update this PR?

[brettstack]

Thanks @davfaulk, could you rebase this on latest develop branch? As James mentioned, we removed redundant file which is the main cause for this conflict.

Rebased off of current develop
