   relationships currently are created using the cypher query below
   
   MATCH( f:<LABEL1> { name: pr.p0 }) 
   MATCH( t:<LABEL2> { name: pr.p1 }) 
   CREATE (f)[r:<RELATIONSHIP>]>(t) 
   SET r.<PROPERTY>= pr.p2
   
   which can cause duplicate relationships 
   
   suggested cypher: 
   
   MATCH( f:<LABEL1> { name: pr.p0 }) 
   MATCH( t:<LABEL2> { name: pr.p1 }) 
   MERGE (f)[r:<RELATIONSHIP> \{PROPERTY: pr.p2}]>(t)
