The views can be closed safely by CloseView() in the order of the first returned array.
For example, if E is composed of A+B joined to C+D, then a possible return value is { {C+D,A+B,C,D,A,B}, {{A,B},{C,D}} }; another possibility is { {C+D,C,D,A+B,A,B}, {{A,B},{C,D}} }.
The second returned array will contain the names of the raw tables only.
