+####Scroll to the underlined element
+Sometime you could need to scroll to the current underlined element, so, to automatically scroll to it once is underlined you can set the options ```{scroll:true, scrollDuration: 500 }```
+```
+var Highlighter = new window.Highlighter({

+  'scrollDuration': 500 //milliseconds
