 ## Overview
 highlightTextarea is a jQuery plugin which allows you to highlight words and sentences inside of <textarea> and <input> elements. Words are defined in a jQuery array and you can customize highlight color and case sensitivity. The highlighting updates itself when typing in the <textarea> and follows scroll and resizing (with jQuery-UI).
