Add new region duplication settings API

[matthewAnsys]

Add new region duplication settings API for Motor-CAD adaptive templates.

This PR includes the following new settings :

• Linked regions -- regions which can be linked to another, so that when duplicated to generate symmetric geometries these regions are united together if touching.
• Singular regions - region which is never united to itself when duplicated.
