#pragma mark ABSTRACT
/*
This class provides parsing functionality that is common to some media data storages provided by Apple
(such as iPhoto and Aperture). Public property list files of iPhoto and Aperture share a lot of structure
(specifically regarding faces data) so you can utilize this intermediate class to share corresponding
functionality between iPhoto and Aperture parsers (and maybe other parsers to come).
ATTENTION: This is an abstract class. Do not use an instance of this class, but use a specific subclass
like IMBiPhotoParser or IMBApertureParser instead...
