use uuid instead incremetal id for nodes

[garanews]

We are playing with data contained in Neo4j deleting and insertimg nodes.
We are having issue with numerical id because the creation node statement uses the len of db as value for id.
Example: inserting 3 nodes (id=1,id=2,id=3) and delete one of them (id=2), when you add a new node it tries to use id=3 that is already present.
Can the use of uuid be a possible solution?
We will play with it tomorrow.
