From d1abe806c54a0c0c845476715e47c52ca48cabab Mon Sep 17 00:00:00 2001
From: David Heinemeier Hansson <david@loudthinking.com>
Date: Thu, 6 Jan 2005 02:31:35 +0000
Subject: Added Base#toggle(attribute) and Base#toggle!(attribute) that makes
 it easier to flip a switch or flag. Added Base#increment!(attribute) and
 Base#decrement!(attribute) that also saves the records. Added
 Base#increment(attribute) and Base#decrement(attribute) that encapsulates the
 += 1 and -= 1 patterns.
