Simple implementation of nested groups

Set::NestedGroups gives an implementation of nested groups, access control lists (ACLs) would be one example of nested groups.

For example, if Joe is a Manager, and Managers have access to payroll, you can create an ACL which implements these rules, then ask the ACL if Joe has access to payroll.

Another example, you may wish to track which city, state and country people are in, by adding people to cities, cities to states, and states to countries.

This module includes some facilities to integrate its data structures with either files in the local filesystem and with tables in a RDBMS.
