+## Setting Options on Initialization
+Whenever you build a plugin that accepts options,
+you should define defaults for as many options as possible,
+then merge the user-provided options with the defaults on initialization.
+It's also a good idea to expose the defaults so that users can even change the default values.
+A common pattern in jQuery plugins looks like this:
+ $.fn.plugin = function( options ) {
+ options = $.extend( {}, $.fn.plugin.defaults, options );
+ // plugin logic goes here
+ };
+ $.fn.plugin.defaults = {
+ param1: "foo",
+ param2: "bar",
+ param3: "baz"
+ };
+The widget factory provides this functionality and even takes it a bit further.
+TODO: Talk about passing multiple option hashes on init.
