Prevent Duplicate Inherited Membership

Use-case: User having a single "Family" relationship type to join all family members.

• Membership type is created with "Family" rel type.
• Father is connected to Child with this rel type.
• Similarly, Mother is connected to Child with the same relationship type.
• When a membership is created on father's contact, this is inherited to Mother and Child's contact.
• Now, when a relationship is created between Mother and Father (same rel type), the membership is duplicated on Mother and Child.
• This extension is to prevent such duplicates to be created, i.e -
• Before creating the inherited membership, it avoid the creation if the contact already has an inherited membership of same type.

The extension is licensed under AGPL-3.0.

Requirements

• PHP v7.0+
