jquery.stretch plugin

This plugin allows vertically stretched layouts, with one or more parts taking up all remaining space. It strives to do only that and leave anything else to the user.

How does it work?

Include the coffee or javascript files in your page, then you get access to the stretch funtion like that:

Assuming html like that:

html  
  head  
    title  
  body  
    #main
      #stretch-me  
      #footer

$("#main").stretch({ // this stretches #main to the window's height
  heightProvider: window // so we don't want to use body's height
});
$("#stretch-me").stretch(); // this stretches stretch-me, but keeps the
                           // footer untouched.

The #footer will keep it's height, defined by css or not, but the #stretch-me element will now expand as much as the viewport allows. This pushes the footer to the bottom of the window.

If you want to keep it that way, if the user resizes his window, you need to make this clear:

var applyLayout = function() {
  $("#main").stretch();
  ...
};
applyLayout();
$(window).resize(applyLayout);

jquery.stretch accepts an options object

• heightProvider: The (usually) parent object that provides the total height. Defaults to the actual parent element, but in case of the body element, in most cases you will want to pass window.
• mode: Accepts "height" and "min-height" (or anything else that can receive an int, but no guarantee for that!).
• fixOverflow: elements with margins within other elements will "leak" their margin to the outside of the container, so jquery.stretch will fix this by adding "overflow: auto" to stretched elements. If you do not want this behavior, set it to false.

Please help!

I am terrible at writing tests (I don't). So if you test this out and do this by writing unit tests, I'd be terribly glad, if you would provide them to me. Just fork this project, clone it, work it and request a merge!
