Please consider support object mapping friendly CURD Methods

Since there is already support for this:
https://github.com/davidmoten/rxjava-jdbc#auto-mappings

``` java
int keyId =
db.update("insert into Person (pid, age, dob, sex, name) values (null, ?, ?, ?, ?) ")
.parameters(person.getAge(), person.getDob(), person.isMale(), person.getName())
.returnGeneratedKeys()
.getAs(Integer.class)
.toBlocking().single();
```

---

Please consider support for a concrete class:

``` java
int keyId =
db.insert(person) // << Object AutoMapped Person for insert.
.returnGeneratedKeys()
.getAs(Integer.class)
.toBlocking().single();
```

Such support will reduce the amount of manual refactoring done for remodeling of Person object which rename or adding fields.
