   *   - add ability to find whitespace problems -> we can build a poor mans decompounder with our index based on a automaton?
   *   - add ability to build different error models maybe based on a confusion matrix?
   *   - try to combine a token with its subsequent token to find / detect word splits (optional)
   *      - for this to work we need some way to defined the position length of a candidate
   *   - phonetic filters could be interesting here too for candidate selection
