Roles and permissions

Because of recent changes that Sam Marshall made to allow visibility of activities and resources to be set at the module level, it opens up new and useful possibilities for using roles to make such items visible to only select groups of individuals.

I have created a new tutorial below demonstrating how to use the feature and would welcome your ideas and feedback.
