RSE Logger API
To log your messages to the workbench log file in .metadata\.log,
either base your plugin class on the org.eclipse.rse.ui.SystemBasePlugin class and use
the inherited logging methods, or instead of instantiating your own Logging object, re-use the
RSE-supplied logging object by calling getDefault().getLog() in the org.eclipse.rse.ui.RSEUIPlugin
class.
