Adding a unique node

[Avron Olshewsky]

All, 

Just "playing" with node and neo4j.

I have managed to save two nodes with a relationship between them.

so I have :

var data1 = { 

         prop1: somevalue1, 

         prop2: somevalue1

}

var data2 = { 

         prop1: somevalue2, 

         prop2: somevalue2

}

var node1 = db.createNode(data1); 

var node2 = db.createNode(data2); 

node1.save( _ );

node2.save( _ );

node1.createRelationshipTo(node2, 'SomeRelationship', {}, _ );

I would like to do the same thing however I would like to ensure that if a new node is created it is unique, is there a simple way to do this ?
