Detailed Description

Class to handle field changes and make them revertable.

The first time a field value is changed the original value is backed up such that it can be restored later on. Restoring will be done at destruction time or using the revert method. It is possible to create a hierarchy of ChangeSets to make interleaved usage possible. It allows to create temporary settings that are reverted to a previous state such that other settings can be used using a basic setting. Each ChangeSet is allowed to have one child only!
