jQuery plugin that creates a 'subquery' object - basically lets you work with a specific chunk of elements or with detached elements in a way that's less annoying.

jquery.subquery.js

jQuery.fn.subquery =  function(){    
    var ctx = $(this);
    return function(){
        return arguments.length ? ctx.find.apply(ctx, arguments) : ctx;
    };
};

// Given something like:
// <article id="article1">
//    <h3>foobar</h3>
// </article>

// var $$ = $('#article1').subquery();
// console.log( $$('h3').text() ); --> 'foobar'
