Title: NPE and Class cast exception

I was getting a class cast exception when trying neo4j query results were being turned into java iterators. The issue is ExecutionContext inherits from MutableMap. Incidentally, you don't need to specify which you're using since you're just using the interface.

Also, passing in null to "new org.neo4j.cypher.ExecutionEngine(gdb,null);" causes a null pointer exception when the executionEngine tries to log. I changed null to be the same as the default argument to the scala constructor.
