[PATCH] Easily subclassable ExtendedEnumType for reusing an existing Enum

                 Key: CAY-1256
             Project: Cayenne
          Issue Type: Improvement
          Components: Cayenne Core Library
            Reporter: Jeremias Maerki

I've had this enum class that has character codes that I use in a CHAR(1) field.

public enum Status {

I didn't want that enum class to introduce a dependency on Cayenne (through the ExtendedEnumeration
interface. So I changed ExtendedEnumType a bit so you can support that enum class with just
a few lines of code and without using ExtendedEnumeration.

Please see the patch for an example. I've written a test case for this although this just
covers the materialization.

In the application code I can now simply do this to register the type:
        node.getAdapter().getExtendedTypes().registerType(new StatusExtendedEnumType());
(my StatusExtendedEnumType is basically the same as the MockEnumWithCodeEnumType in the patch)

I hope you find this useful, too. Patch is against Cayenne Trunk.
