/*
*   Configuration
*   =============
*
*   @cfg {String} trigger
*   Default value is 'hover focus'.
*   Describes how tooltip is triggered - click | hover | focus | manual. 
*   You may pass multiple triggers; separate them with a space
*
*   @cfg {String} title
*
*   @cfg {Boolean} arrow
*   Default value is 'false'.
*   If 'true', shows an arrow that point to the parent component.    
*
*   @cfg {String} placement
*   Default value is 'top'.
*   Describes tooltips position relatively of the parent component
*   acceptable values: 'top', 'bottom', 'right', 'left', 
*                        'top-right/left', 'bottom-right/left', 'cursor'
*   If placement = 'cursor', tooltip doesn't arrange position relatively 
*   of the parent and shows relatively of the cursor position.    
*
*   @cfg {String} cls
*   An extra CSS class that will be added to tooltip dom-element.
*
*   @cfg {Boolean} html
*   Default value is 'false'.
*   Insert HTML into the tooltip. If false, jQuery's text method will be used 
*   to insert content into the DOM
*
*
*   Events
*   ======
*
