Coverage increased (+0.3%) to 87.244% when pulling b7334f7 on remove-relationship into 8b4acbf on master.

What is the logic behind this one?
What is a use case when the lib would have to take care of deleting relationships?

If I understood correctly, you want to delete one relationship from a model. In that case a better solution would be deleting the relationship model itself.

I might be wrong but this might be related with the following issue.
Let's say you have a tree structure of nodes. Each node can have a parent node and can have multiple children nodes.
Let's say you have a "node A" that is the parent of "node B".
How do you remove the parent relationship from "node B"?

I didn't had time to test this branch yet, but I'm having this kind of issue in one of my projects right now.

Would be great if this could get in 😃

Removing existing relations is currently not possible and that's a real missing feature

PR is not complete (anymore). I added the changes to my project, so I could make use of this feature. I needed to check if the relationshipModel did exist in the updateRelationships function as well (line 436).
