To support storing of a classes' state to an INIFile, derive
from this class and implement the getValue/setValue-methods.
Note that a more sophisticated and simpler to use scheme for
storing state that is accessible through GUI elements, e.g.,
LineEdits, already exists in libVIEW. Use this class if you
want/need to be independent of the view functionality, or if
the elements supported by VIEW::PreferencesEntry do not suffice.
Make sure to name all derived objects, by calling setObjectName()
Otherwise (re-)storing the values wont work.
