Write a jQuery plugin that makes an element act like a <blink>
tag. It should work for any arbitrary speed.

Make plugin work for selectors that correspond to a single element.
// show/hide every 1000ms
jQuery('.myDiv').blink(1000);
// twice as fast
jQuery('.otherDiv').blink(500);
Make plugin work for selectors that correspond to multiple elements.
jQuery('div').blink(1000);
