overflowy - jquery plugin 

this is a really simple plugin to allow you to specify block elements 
with a defined height that should hide any overflowing content 
and display ellipsis (ie, ...) underneath.

Notes:

this is alpha quality code only.

probably wildly inefficient as it changes the elements to overflow-y:scroll and
back to hidden - causing reflow, but it works for my requirements in FF3.6+, 
IE6+, Chrome5+. I couldnt get other similar plugins (autoellipsis, threedots, 
text-overflow, textOverflow, truncator etc) to work exactly for my project 
- especially a requirement that the content could include images and other 
markup aswell as inline text. 

TODO: 
1) test performance 
2) make the ellipsis configurable

Usage:

1) Include the script (after jquery), for example:
<script src="jquery.overflowy.min.js"></script>

2) make sure your elements divs have a height set, for example:
<style>
    .mystuff { height: 2em; }
</style>

<div class="mystuff">blabla1<br/>blabla2<br/>blabla3<br/>blablabla4<br/></div>

3) Apply to your elements with a selector
<script>
    $(function(){
        $('.mystuff').overflowy();
    });
</script>

4) Specify some settings (eg resetHeight auto resizes height if theres no overflow)
<script>
    $(function(){
        $('.mystuff').overflowy({resetHeight:true});
    });
</script>
