+/**
+	_onyx.Picker_, a subkind of <a href="#onyx.Menu">onyx.Menu</a>, is used to
+	display	a list of items that can be selected. It is meant to be used in
+	conjunction with an	<a href="#onyx.PickerDecorator">onyx.PickerDecorator</a>.
+	The decorator loosely couples the Picker with an
+	<a href="#onyx.PickerButton">onyx.PickerButton</a>--a button that, when
+	tapped, shows the picker. Once an item is selected, the list of items closes,
+	but the item stays selected and the PickerButton displays the choice that
+	was made.
+
+	To initialize the Picker to a particular value, set the _active_ property to
+	true for the item that should be selected.
+	
+		{kind: "onyx.PickerDecorator", components: [
+			{}, //this uses the defaultKind property of PickerDecorator to inherit from PickerButton
+			{kind: "onyx.Picker", components: [
+				{content: "Gmail", active: true},
+				{content: "Yahoo"},
+				{content: "Outlook"},
+				{content: "Hotmail"}
+			]}
+		]}
+
+	Each item in the list is an <a href="#onyx.MenuItem">onyx.MenuItem</a>, so
+	an _onSelect_ event with the item can be listened to by a client application
+	to determine which picker item was selected.
