I previously was using the following inline:
```
new URLClassLoader(...) {
def addNewUrl(url: URL) = this.addURL(url)
}
```
But I was unable to access the exposed method since it was creating an
anonymous subclass. In terms of providing a trait versus a class that extends
URLClassLoader, I figured a trait was a lighter way to mix in the needed
exposure.
