// Here is the full source
// Supports the follow selector methods:
//
// $("#id"); Selects elements with id "id"
// $(".class"); or $("element.class"); to select by class
// $("//element[@attr='value']"); supports XPath queries. Note: Script automatically prefixes a '.' to keep within context
//
// $("#id", context); Selects elements with id 'id' within 'context'
//
// $("#id || element.class || //element[@attr='value']"); You can pipe selectors together with ' || '
//
// Method's:
// $('.class').hide(); Will hide all selected elements. Pass the function a number corresponding to milliseconds to fade out element
// $('.class').show(); Show hidden elements. Pass the function a number corresponding to milliseconds to fade in element
// $('.class').count(); Returns number of elements
// $('.class').css({property: "value", fontWeight: "bold"}); Set CSS values of selected elements
// $('.class').bind('click', handler); Attaches event listener's to the selected elements
// $('.class').remove(); Removes selected elements from the DOM
// $('.class').append(element); Appends a element to selected elements
// $(context).find('.class'); Same as $('.class',context);
// $('.class').animate({opacity:"0",height:"0px"},2000,fn); Animations!
// $('.class').html('Hey!'); Set's the innerHTML. Having no parameter will pass the HTML of the first result.
