Copy constructors

[Tom Schindl]

So how do image the FXML to look like? You need something like a
for-loop in FXML which makes it a JSP like thing which is not good IMHO
- I'm even not 100% sold on the new binding syntax but - having for, if,
... is IMHO going to be a disaster.

If something needs logic and expressions, then express it in a
programming language like Java, ... but not in a markup one.
