 /**

  * This example has the following tests

  * 

  * testBasicListener

  * 

  * When we create SysUnderTest, in setup we expected it to add

  * a LegacyDisplayListener to the legacy system.  In setup, we retrieved

  * that listener so in the test we can now fire display update events

  * and make sure the system does update the display.

  * 

  * testTwoClearEvents

  * 

  * In this test, we want to make sure that if the legacy system fires

  * two clear events the system still works and there are no exceptions from

  * our system back to the legacy system.
