Mutations are regular-expression-based replacements that are applied
after variants have been computed. They are meant to be used for
variations on character level.
Add spelling variations for German umlauts.
Adds a tagger for names by language so that the analyzer of that
language is used. Thus variants are now only applied to names
in the specific language and only tag name tags, no longer to
reference-like tags.
Implements per-name choice of analyzer. If a non-default
analyzer is choosen, then the 'word' identifier is extended
with the name of the ana;yzer, so that we still have unique
items.
Adds a second callback for the analyzer which is responsible
for parsing the configuration rules and converting it to
whatever format necessary. This way, each analyzer implementation
can define its own configuration rules.
Adds a mandatory section 'analyzer' to the token-analysis entries
which define, which analyser to use. Currently there is exactly
one, generic, which implements the former ICUNameProcessor.
