JPAProducer $select and $expand algorithm incorrect


I have some examples of $select and $expand that do not work according to the 
spec:

This still selects all properties of Orders instead of just the OrderID:
    http://localhost:8886/JPAProducerExample.svc/Customers?$format=json&$expand=Orders&$select=Phone,CustomerID,Orders/OrderID

This does not expand Orders/OrderDetails, it does expand Orders/Employee 

    http://localhost:8886/JPAProducerExample.svc/Customers%28%27ALFKI%27%29?$format=json&$expand=Orders,Orders/OrderDetails,Orders/Employee&$select=CustomerID

This expands Orders even though it is not selected.

    http://localhost:8886/JPAProducerExample.svc/Customers%28%27ALFKI%27%29?$format=json&$expand=Orders&$select=CustomerID

I have a new class called PathHelper that implements the $select and $expand 
algorithms in a handy form that is re-usable by any producer PathHelper will be 
checked in in a day or so.
