-====Internals
-* Use printLog() in assertion functions.
-* Use a separate flag for rail problems in RackObject.
-* Use user ID instead of username where possible.
-* Search function is called 4 times per 1 search (see functions.php).
-* renderIPRange() could use printRefsOfType()
-* Should getObjectAddressesAndNames() be replaced with getObjectAddresses()?
-* Check that ophandlers.php:addNewRange() employs assertions properly.
-* Clean up pagehandlers.php from pointless endless case constructs (most probably with a help of new "tabhandler" navigation index).
-* Look if foreach(getPortTypes()) can be replaced with more standard printSelect()
