## Detailed Description

This is a base class of the RelationsManager class template. It contains databases for the relations and the members that we need to keep track of and handles the ouput buffer. Unlike the RelationsManager class template this is a plain class.

Usually it is better to use the RelationsManager class template as a basis for your code, but you can also use this class if you have special needs.
