    /**
     * Simple plugin for using an Ext.tip.Tip with a slider to show the slider value. In general this class is not created
     * directly, instead pass the {@link Ext.slider.Multi#useTips} and {@link Ext.slider.Multi#tipText} configuration
     * options to the slider directly.
     *
     *     @example
     *     Ext.create('Ext.slider.Single', {
     *         width: 214,
     *         minValue: 0,
     *         maxValue: 100,
     *         useTips: true,
     *         renderTo: Ext.getBody()
     *     });
     *
     * Optionally provide your own tip text by passing tipText:
     *
     *     @example
     *     Ext.create('Ext.slider.Single', {
     *         width: 214,
     *         minValue: 0,
     *         maxValue: 100,
     *         useTips: true,
     *         tipText: function(thumb){
     *             return Ext.String.format('**{0}% complete**', thumb.value);
     *         },
     *         renderTo: Ext.getBody()
     *     });
