+/**
+ * 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.
