//Quick Element Contruction Syntax

//Instead of concatenating strings together to build up new HTML elements, 
//you can now utilize a new feature inside of jQuery 1.4 for quick element construction. 
//You can pass a map of properties as the second parameter to set attributes and wire-up event handlers 
//Keep in mind certain elements cannot be created this way due to limitations in some browsers (Internet 
//Explorer for example). Elements you will have trouble with include `input` and `button` elements.
