How do I apply style and select the language?

Hey I'm using your code for my script editor, but I can't seem to be able to select the lanugage.

```java
textArea = new SyntaxTextAreaFX();
textArea.setCodingStyle(LANGS.javascript);
```

What is wrong with this? I ran your example code and it highlight the .c file just fine.
Also, how can I apply my own style to the background etc?
