To test:

1. Check that the unit tests pass
2. Run the following python script, No messages should come onto the log at Notice level, (you can still see the parameters if you lower your log level if you wnat to check that logging was still working).

   palg = AlgorithmManager.create("Pause")
   print palg.getAlgStartupLogging()
   palg.setAlgStartupLogging(False)
   print palg.getAlgStartupLogging()
   palg.execute()

When running with the option disabled I still get an entry in the log, all be it an empty one, but it does add blocks of white space to the Results Log.

Updated to test

1. Check that the unit tests pass
2. Run the following python script, No messages should come onto the log at Notice level.

   #This should log nothing
   palg = AlgorithmManager.create("Pause")
   print palg.getAlgStartupLogging()
   palg.setAlgStartupLogging(False)
   print palg.getAlgStartupLogging()
   palg.execute()
   
   #this should log only the messages from inside the alg itself or errors
   #the highest level message is Information in this example
   palg = AlgorithmManager.create("LoadRaw")
   palg.setProperty("Filename","CSP78173")
   palg.setProperty("OutputWorkspace","output")
   print palg.getAlgStartupLogging()
   palg.setAlgStartupLogging(False)
   print palg.getAlgStartupLogging()
   palg.execute()
