| A CharTransformer which wraps N other CharTransformers, and links them with N - 1 new Threads,
effectively working as a 'chained' transformer.
The first transformation is done by the ChainedCharTransformer instance itself, after starting
the N - 1 Threads for the other N - 1 transformations.
If no CharTransformers are added, and 'transform' is called, logically, nothing will happen. Add
the CopyCharTransformer if necessary.
Schematicly:
new ChainedCharTransformer().add(T1).add(T2)....add(TN).transform(R, W);
