-/**
- *  Normalizer for Arabic.
- *  <p>
- *  Normalization is done in-place for efficiency, operating on a termbuffer.
- *  <p>
- *  Normalization is defined as:
- *  <ul>
- *  <li> Normalization of hamza with alef seat to a bare alef.
- *  <li> Normalization of teh marbuta to heh
- *  <li> Normalization of dotless yeh (alef maksura) to yeh.
- *  <li> Removal of Arabic diacritics (the harakat)
- *  <li> Removal of tatweel (stretching character).
- * </ul>
