> ability to either override findBy/findAll methods with @Query annotation (without using params or using params, but also allowing the E example pattern)  or add support for custom method expression that could be used for this purpose.  the E example would only appy to the main Entity restrictions, the additional params could apply to nested entities based on param index
> ie. @Query(value = "select r from Range r where r.customId IN (select e.customId from EbsUserStub e)")
> 	public abstract List<Range> findBy(Range paramE, SingularAttribute<Range, ?> paramArrayOfSingularAttribute);
> or 
> @Query(value = "select r from Range r where r.customId IN (select e.customId from EbsUserStub e)")
> 	public abstract List<Range> findUsing(Range paramE, SingularAttribute<Range, ?> paramArrayOfSingularAttribute);
> or 
> @Query(value = "select r from Range r where r.customId IN (select e.customId from EbsUserStub e where e.miscField = ?2)")
> 	public abstract List<Range> findByMiscField(Range paramE, SingularAttribute<Range, ?> paramArrayOfSingularAttribute, String miscField);
> method expression could either be custom ie. findUsing,  findByEntityName, findByMiscField or some other marker.
