grouperSession should be easier to use if not sure if open

The old way was something like this:

boolean startedRootSession = false;
//dont assign if creating a new one
GrouperSession theGrouperSession = GrouperSession.staticGrouperSession(false);
try {
if (theGrouperSession == null)

{ startedRootSession = true; theGrouperSession = GrouperSession.startRootSession(); }

// do work
} finally {
if (startedRootSession)

{ GrouperSession.stopQuietly(theGrouperSession); }

}
