testUseFilterToStopAMessage()method 
public function testUseFilterToStopAMessage():void

Test using a filter function to stop propagation of a message.

The way to stop propagation of a message from within a filter is to throw an error from the filter function. This test creates two NORMAL messages, each with header objects that contain a bozoLevel property. One has this property set to 10, the other to 3.

Creates a Filter, named 'bozoFilter' with an anonymous pipe listener feeding the output back into this test. The filter funciton is an anonymous function that throws an error if the message's bozoLevel property is greater than the filter parameter bozoThreshold. the anonymous filter parameters object has a bozoThreshold value of 5.

The messages are written to the filter and it is shown that the message with the bozoLevel of 10 is not written, while the message with the bozoLevel of 3 is.
