## Autosize Small jQuery plugin to allow dynamic resizing of textarea height, so that it grows as based on visitor input. To use, just call the `.autosize()` method on any textarea element. Example `$('textarea').autosize();`. See the [project page](http://jacklmoore.com/autosize/) for documentation, caveats, and a demonstration.
