General Issue: Add comments to raw-data/create_adams_data.R?

[jimrothstein]

Background Information

This is good code, but might benefit from a small number of comments.

This script locates and runs ADaM templates in the various admirals packages.
A few comments would aid in future maintenance.

Examples:

• system.file(package = 'pkg') returns? [depends on whether load_all() has run]
• generally clarify which files and paths [often it is where the package is installed]

Definition of Done

no more than a few comments
