+/**
+ * This plugin inserts the right avatar for the user, depending on, whether a
+ * custom avatar is uploaded - which it uses then - or not, and display a
+ * placeholder with the first letter of the users name instead.
+ * For this it queries the core_avatar_get route, thus this plugin is fit very
+ * tightly for owncloud, and it may not work anywhere else.
+ *
+ * You may use this on any <div></div>
+ * Here I'm using <div class="avatardiv"></div> as an example.
+ *
+ * There are 4 ways to call this:
+ *
+ * 1. $('.avatardiv').avatar('jdoe', 128);
+ * This will make the div to jdoe's fitting avatar, with a size of 128px.
+ *
+ * 2. $('.avatardiv').avatar('jdoe');
+ * This will make the div to jdoe's fitting avatar. If the div aready has a
+ * height, it will be used for the avatars size. Otherwise this plugin will
+ * search for 'size' DOM data, to use for avatar size. If neither are available
+ * it will default to 64px.
+ *
+ * 3. $('.avatardiv').avatar();
+ * This will search the DOM for 'user' data, to use as the username. If there
+ * is no username available it will default to a placeholder with the value of
+ * "x". The size will be determined the same way, as the second example.
+ *
+ * 4. $('.avatardiv').avatar('jdoe', 128, true);
+ * This will behave like the first example, except it will also append random
+ * hashes to the custom avatar images, to force image reloading in IE8.
