| /** Example user_groups.cpp \file user_groups.cpp |
| \brief Shows the availability of set operations on interval maps. |
| |
| In the example there is a user group 'med_users' of a hosptial staff |
| that has the authorisation to handle medical data of patients. |
| User group 'admin_users' has access to administrative data like |
| health insurance and invoice data. |
| |
| The membership for each user in one of the user groups has a time |
| interval of validity. The group membership begins and ends. |
| |
| Using a union operation '+' we can have an overview over both |
| user groups and the membership dates of employees. |
| |
| Computing an intersection '&' shows the super users. The persons |
| that are members of both med_users and admin_users and the times |
| of the joint memberships. |
