<p>Instantiated once per running application, it holds a reference to every high-level object
whose reference needs to be held: <a class="reference internal" href="results.html#core.results.Results" title="core.results.Results"><code class="xref py py-class docutils literal notranslate"><span class="pre">Results</span></code></a>,
<a class="reference internal" href="directories.html#core.directories.Directories" title="core.directories.Directories"><code class="xref py py-class docutils literal notranslate"><span class="pre">Directories</span></code></a>, <a class="reference internal" href="gui/index.html#module-core.gui" title="core.gui"><code class="xref py py-mod docutils literal notranslate"><span class="pre">core.gui</span></code></a> instances, etc..</p>
<p>It also hosts high level methods and acts as a coordinator for all those elements. This is why
some of its methods seem a bit shallow, like for example <a class="reference internal" href="#core.app.DupeGuru.mark_all" title="core.app.DupeGuru.mark_all"><code class="xref py py-meth docutils literal notranslate"><span class="pre">mark_all()</span></code></a> and

they are also followed by a notification call which is very important if we want GUI elements
to be correctly notified of a change in the data theyre presenting.</p>
