RepositoryOperations (Oncoblocks: Centromere Core 0.3.0 API)

```
public interface RepositoryOperations<T,ID extends Serializable>
```
Basic operations that all repositories must implement, regardless database technology used. Based on PagingAndSortingRepository, but with some additions to support dynamic queries, and removing some JPA-specific functionality.
