+ * A music index is a mapping from an index string to a list of prefixes.  A complete index consists of a list of

+ * <p/>
+ * For a normal alphabetical index, such a mapping would typically be <em>"A" -&gt; ["A"]</em>.  The index can also be used
+ * to group less frequently used letters, such as  <em>"X-&Aring;" -&gt; ["X", "Y", "Z", "&AElig;", "&Oslash;", "&Aring;"]</em>, or to make multiple
+ * indexes for frequently used letters, such as <em>"SA" -&gt; ["SA"]</em> and <em>"SO" -&gt; ["SO"]</em><p/>
+ * <p/>
+ * Clicking on an index in the user interface will typically bring up a list of all music files that are categorized
+ * under that index.
