Working spelling corrector.

It's not perfect yet, but it works.

You should have a corpus to train the spelling corrector on. One is already in the repository (big.txt), so download it and train using it. Unfortunately, there is no persistent data store yet, so you have to retrain every time you want to use the spelling corrector.

The spelling corrector is not perfect yet. It only corrects words (sentences should be an easy addition), and is slow sometimes.

Have fun using it.
