ability to clean up log files produced during testing

pduLog/README.md

+# PDU Log Files
+
+This directory holds temporary PDU log files which may be deleted at any time!
+
+Each time you run a DIS simulation and a PduRecorder is listening, another
+log file is created.  File names are numbered sequentially and uniquely, so that 
+important PDU log captures can later be copied and saved to where they are needed.
+
+[ExamplePduCaptureLog.dislog](ExamplePduCaptureLog.dislog) shows an example log file.
+
+Be sure to save your work, when appropriate, by copying log files of interest to
+the corresponding homework or project directory (and likely renaming as well).
+
+Note that the PDU log files are very tolerant of inline comments starting with
+a # character, so you can document success/failure and TODO issues there as well.
+
+To clean out old log files, simply run [build.xml](build.xml) target `clean.all.log.files`
