## Merge multiple concepts (and delete others).ajs
// Merge multiple concepts (and delete others)
//
// Requires jArchi - https://www.archimatetool.com/blog/2018/07/02/jarchi/
//
// This script merges multiple concepts (and delete others)
//
// Version 1.1 (2020/01/20) Add an option to keep only the content of the "target" concept
// Version 1.0 (2019/11/12) First version published
//
// Known limitation: works only on elements, not relationships
//
