It provides a trait that can be used by model classes to add functions and variables to perform several types of operations between different model objects that have some kind of relationship between them. Currently it can:

- Attach one or more model objects to a given parent model object
- Detach one or more model objects from a given parent model object
- Retrieve one or more parent object of another object
- Attach one or more child model objects to a given model object
- Detach one child model object from a given parent model object
- Retrieve one or more children model objects from a given parent model object

This package provides a trait that can be used in model classes, so you can hierarchical relationships between parent and child objects.
