/* Delete duplicated relationship.ajs
 *
 * This jArchi script scans all the model elements and merge identical relationships.
 *    relastionships are considered as identical if name, type, source and target are identical.
 *
 * Impact on model:
 *   When elements are merged, the properties, documentations and relationships are merged. The specialization of the first element found in the model is kept.
 *
 * Impact on views:
 *   No impact.
 * 
 * Versions
 *      1.0     20/07/2023    Sebastien Dubourdieu      First script release
