Title: Fixed small typo in documentation

Hey,

Love the library! Thank you for creating and maintaining it. Just thought I would fix a small problem with the documentation I came across today. When loading a classifier from a raw JSON string the JSON string needs to be parsed first or else it throws this error:
```
/home/jkimbo/code/categories/node_modules/natural/node_modules/apparatus/lib/apparatus/classifier/logistic_regression_classifier.js:174
classifier.__proto__ = LogisticRegressionClassifier.prototype;
^
TypeError: Cannot set property '__proto__' of undefined

```

Thanks again!
