Framework to simplify code for ODocumentWrappers and other DAO

[Ilia Naryzhny]

Will be cool to have something like:

@ProvidedBy(ODocumentWrapperProvider.class)
public interface IOPerspective extends IODocumentWrapper {
	public String getAlias();
	public Map<String, Object> getName();
	
	default public String getTestAlias() {
		return "test"+getAlias();
	}
	
	default public String getTest2Alias() {
		return "test2"+getDocument().field("alias");
	}
	
	default public String getTest3Alias() {
		return "test3"+getTestAlias();
	}
	
	@Lookup("select from OPerspective where alias = :alias")
	public void lookup(String alias);
	
	@Query("select expand(menu) from OPerspective where @rid = :target")
	public List<ODocument> listAllMenu();
	
	public List<ODocument> getMenu();
	
}

and

@ProvidedBy(DAOProvider.class)
public interface ITestDAO {

	@Query("select from OPerspective")
	public List<ODocument> listOPerspective();
	
	default public int countPerspectives() {
		return listOPerspective().size();
	}
}
