This is an implementation of Norvig's spellchecker [1] based
on Joe Sander's port to PHP [2].
Main differences from Joe's try:
- the code is wrapped in an class
- it's working
- i rewired some of the algorhithms to be closer to what Norvig
suggested
known shortcommings:
- it's slow
- it needs lots of RAM, i run it via the php-cli with a memory limit of 512MB
