Dummy

```
public class Dummy
extends java.lang.Object
```
Used by RowAtom. The "textSymbol"-property and the type of an atom can change (according to the TeX-algorithms used). Or this atom can be replaced by a ligature, (if it was a CharAtom). But atoms cannot be changed, otherwise different boxes could be made from the same TeXFormula, and that is not desired! This "dummy atom" makes sure that changes to an atom (during the createBox-method of a RowAtom) will be reset.
