Refactoring

From what I've read, doing string+string+string is basically the same as what you did with Stringbuilder and the compiler takes care of the work while leaving the code to be more readable.

From: http://stackoverflow.com/questions/8725739/correct-way-to-use-stringbuilder

Something like this:
```
return "prefix " + variable1 + " middle " + variable2 + " end";
```
It roughly translates to:
```
StringBuilder tmp = new StringBuilder(); // Using default 16 character size
tmp.append("prefix ");
tmp.append(variable1);
tmp.append(" middle ");
tmp.append(variable2);
tmp.append(" end");
return tmp.toString();
```

Thoughts?
