[Fields] Embedding Fields

As an association field, this field is used to link concepts together.

What's different about embedding is that there is a parent-child relation between the two concepts.

Take for example Concept A that has an embedding field with Concept B. Therefore, an instance of Concept B can be embedded by an instance of Concept A. If so:

• That instance cannot be embedded by any other instance.

• If the instance of Concept A is deleted, the embedded instance of Concept B will be automatically deleted as well.
