Added new tools for grant_everyone_(editor,viewer)_access.rb
update_project_permissions.rb - makes a summarize_project_permissions.rb: script to summarize Permissions for all Users within a Project of interest. Includes Admins - this is an audit-quality script, whereas user_permissions_summary.rb summarizes permissions only for Users that have access.
- update_project_permissions.rb: script to update Permissions for all non-Admin users already existing in a Project, to an updated value of interest.
- user_permissions_summary_selected.rb: script to summarize permissions only for a select list of users specified in an input CSV file
