[PATCH] Mutators for warp-persist.

[GoogleCodeExporter]

Mutators will allow batch DML operations via the Dynamic Finders facility
in warp.

In any location where you might be able to apply a @Finder, you should be
able to apply a @Mutator with a delete or update operation :

@Transactional
@Mutator("update MyEntity me set me.employeeClass = :class where me.salary
> :salary")
int updateClassBasedOnSalary(@Named("class") String employeeClass,
@Named("salary") Double salary);

Please note that the @Transactional attribute may need to be present based
on how your transactional functionality is set up.

Also, the return value is pre-determined (usually an int ) based on the
executeUpdate semantics of both Hibernate and JPA.

As noted in my group post, some of the changes in this patch are naming changes 
to be
more generic, such as moving FinderDescriptor to MethodDescriptor, and changing
variable names similarly. ( I think that's the only one )

Are there any tests that cover this?

it's been a little while, but I'm pretty sure I added to your test suite to try 
this out.

Let me recheck and reup ( and sync up the code with trunk ).

If there is no interest in this issue I'd like to close it out?
