Description

1. Make ResultIterator implement Iterable<T> to simplify its use in loops.

2. Create ObjectContext.iterator method that is available both in ROP and server stacks. CayenneContext can simply do something stupid, like iterating over a regular list.

3. Create a callback flavor - ObjectContext,iterate(Select, ResultIteratorCallback)

4. Move ResultIterator to org.apache.cayenne - it should be available to all layers.

5. Stop throwing CayenneException from all methods.
