/**
 * A ResultPrinter that prints nothing. This exists, in order to provide a replacement to JUnit's ResultPrinter, which
 * is refered to directly by JUnit code, rather that as an abstracted TestListener. JUnit's text ui TestRunner must have
 * a ResultPrinter. This provides an implementation of it that prints nothing, so that a better mechanism can be used
 * for providing feedback to the console instead.

 * @todo   See todo in TKTestRunner about completely replacing the test ui runner. Doing things like this in order to
 *         extend JUnit is not nice, and there needs to be a better way to do it. Delete this class and use a listener
 *         instead.
