void addRelation(const TObject *fromObject, StoreEntry *&fromEntry, int &fromIndex, const TObject *toObject, StoreEntry *&toEntry, int &toIndex, float weight, const std::string &namedRelation)
Add a relation from an object in a store array to another object in a store array.

Copies all relations of sourceObj (pointing from or to sourceObj) to this object (including weights).

Useful if you want to make a complete copy of a StoreArray object to make modifications to it, but retain all information on linked objects.

Note: this only works if sourceObj inherits from the same base (e.g. RelationsObject), and only for related objects that also inherit from the same base.
