TableViewBuilder idea

[Thiago Milczarek Sayão]

Probably goes on a library. But it would also be nice to have to boost
productivity on enterprise applications, boosting JavaFX adoption.

The idea is not to map directly to JavaFX observables because it would
imply importing it on the "backend logic". But just copy from a DTO to an
observable class and the UI would auto-update.

It can come from a database or a web-service.
