Description
Currently, the classes in opennlp.tools.stemmer.snowball.* do not follow the Java Naming Conventions.
There is no requirement, that they start with a lower-cased letter (from a generation perspective). To make it consistent, we should capitalize the first letter of the related classnames.
In addition, we should make them package-private, so people use these stemmers only over the related abstraction.
