<p>
This class provides methods for requesting information
about the UI capabilities of the source, and defines the
expectations that apply to all sources - that they will
provide <a class="link" href="RBEntryView.html" title="RBEntryView"><span class="type">RBEntryView</span></a> and <a class="link" href="RhythmDBQueryModel.html" title="RhythmDBQueryModel"><span class="type">RhythmDBQueryModel</span></a> objects, mostly.
</p>
<p>
Many of the methods on this class come in can_do_x and do_x
pairs.  When can_do_x always returns FALSE, the class does not
need to implement the do_x method.

Useful subclasses include <a class="link" href="RBBrowserSource.html" title="RBBrowserSource"><span class="type">RBBrowserSource</span></a>, which includes a <a class="link" href="RBLibraryBrowser.html" title="RBLibraryBrowser"><span class="type">RBLibraryBrowser</span></a>
and takes care of constructing an <a class="link" href="RBEntryView.html" title="RBEntryView"><span class="type">RBEntryView</span></a> too; <span class="type">RBRemovableMediaSource</span>,
which takes care of many aspects of implementing a source that represents a
