Thanks for the Javadoc added previously. Perhaps add a section on how to
use this class. If I need a test directory, do I create an instance of this
class? Or, does JUnit do it for me? If done automagically, how do I get a copy
of the directory?
If this is explained in JUnit, perhaps just reference that information.
Even better would be a short example:
> To get a test directory:
```
// Do something here
File myDir = // do something
```
