Method to clear classifier

[cryptiklemur]

Would it be too much trouble to make a public method that clears all the learned phrases?

@aequasi why not create a new classifier instead?

I ported this library into PHP and added the reset method. https://github.com/niiknow/bayes/blob/master/src/Bayes.php#L63

This is simply move everything in the constructor into it's own method and call that from the constructor. But derhuerst has a better workaround/suggestion.
