The editor allows the creation of two «mediation» relationships x and y having the same ground, i.e., domain(x) = domain(y) and codomain(x) = codomain(y).

What steps will reproduce the problem?
1. Create a «relator»;
2. Create a class, e.g., a «role»;
3. Create a «mediation» relationship from the «relator» to the «role»;
4. Create another «mediation» relationship from the «relator» to the 
«role»;

What is the expected output? What do you see instead?
The creation of the second «mediation» relationship should be forbidden 
because it has the same meaning of the first «mediation» relationship.
