Allow properties to be nil

Reported by Andreas Ronge | November 16th, 2010 @ 09:51 AM

The Neo4j:Model allows to set if a property should allow to be null (null is same as nil, I guess) or not.

property :title, :default => "Mr", :length => 3, :null => false

but if a property is nil then the property will be deleted.
It is currently impossible to detected if a property is nil or if it does not exist.
Not sure if this is a problem.
