This class computes the serial version UID of a class modeled by a
ClassEditor. Otherwise, we would have to load the class in
order to compute its serial version UID. That would suck.
The algorithm for computing the serial version UID can be found in the serialization
spec
Returns the serial version UID of the class modeled by the given
ClassEditor.
Parameters: ce - The class must implement java.io.SerializableSerializable
