A lot of functionalities of the App are implemented in the platform-specific subclasses of
``app.DupeGuru``, like ``app_cocoa.DupeGuru``, or the ``base.app.DupeGuru`` class in the PyQt
codebase. For example, when performing "Remove Selected From Results",
``app_cocoa.Dupeguru.RemoveSelected()`` on the Obj-C side, and
``base.app.DupeGuru.remove_duplicates()`` on the PyQt side, are respectively called to perform the
thing. All of this is quite ugly, I know (see the "Refactoring" section below).

A lot of operations in dupeGuru take a significant amount of time. This is why there's a generalized
threaded job mechanism built-in ``app.DupeGuru``. First, ``app.DupeGuru`` has a ``progress`` member
which is an instance of ``jobprogress.job.ThreadedJobPerformer``. It lets the GUI code know of the
progress of the current threaded job. When ``app.DupeGuru`` needs to start a job, it calls

``_start_job()`` and the platform specific subclass deals with the details of starting the job.
Core principles
---------------
The core of the duplicate matching takes place (for SE and ME, not PE) in ``dupeguru.engine``.
There's ``MatchFactory.getmatches()`` which take a list of ``fs.File`` instances and return a list
of ``(firstfile, secondfile, match_percentage)`` matches. Then, there's ``get_groups()`` which takes
a list of matches and returns a list of ``Group`` instances (a ``Group`` is basically a list of
``fs.File`` matching together).
The core of the duplicate matching takes place (for SE and ME, not PE) in :mod:`core.engine`.
There's :func:`core.engine.getmatches` which take a list of :class:`core.fs.File` instances and
return a list of ``(firstfile, secondfile, match_percentage)`` matches. Then, there's
:func:`core.engine.get_groups` which takes a list of matches and returns a list of
:class:`.Group` instances (a :class:`.Group` is basically a list of :class:`.File` matching
together).
When a scan is over, the final result (the list of groups from ``get_groups()``) is placed into
``app.DupeGuru.results``, which is a ``results.Results`` instance. The ``Results`` instance is where
all the dupe marking, sorting, removing, power marking, etc. takes place.
When a scan is over, the final result (the list of groups from :func:`.get_groups`) is placed into
