nl.captcha.Captcha
A builder for generating a CAPTCHA image/answer pair.
Example for generating a new CAPTCHA:
```
Captcha captcha = new Captcha.Builder(200, 50) .addText() .addBackground() .build();
```
Note that the build() must always be called last. Other methods are optional, and can sometimes be repeated. For example:
```
Captcha captcha = new Captcha.Builder(200, 50) .addText() .addNoise() .addNoise() .addNoise() .addBackground() .build();
```
Adding multiple backgrounds has no affect; the last background added will simply be the one that is eventually rendered.

To validate that answerStr is a correct answer to the CAPTCHA:
captcha.isCorrect(answerStr); @author James Childersv
