dojo.NodeList = function(){
// summary:
// dojo.NodeList is an of Array subclass which adds syntactic
// sugar for chaining, common iteration operations, animation, and
// node manipulation. NodeLists are most often returned as the
// result of dojo.query() calls.
// description:
// dojo.NodeList instances provide many utilities that reflect
// core Dojo APIs for Array iteration and manipulation, DOM
// manipulation, and event handling. Instead of needing to dig up
// functions in the dojo.* namespace, NodeLists generally make the
// full power of Dojo available for DOM manipulation tasks in a
// simple, chainable way.
// example:
// create a node list from a node
// | new dojo.NodeList(dojo.byId("foo"));
// example:
// get a NodeList from a CSS query and iterate on it
// | var l = dojo.query(".thinger");
// | l.forEach(function(node, index, nodeList){
// | console.log(index, node.innerHTML);
// | });
// example:
// use native and Dojo-provided array methods to manipulate a
// NodeList without needing to use dojo.* functions explicitly:
// | var l = dojo.query(".thinger");
// | // since NodeLists are real arrays, they have a length
// | // property that is both readable and writable and
// | // push/pop/shift/unshift methods
// | console.log(l.length);
// | l.push(dojo.create("span"));
// |
// | // dojo's normalized array methods work too:
// | console.log( l.indexOf(dojo.byId("foo")) );
// | // ...including the special "function as string" shorthand
// | console.log( l.every("item.nodeType == 1") );
// |
// | // NodeLists can be [..] indexed, or you can use the at()
// | // function to get specific items wrapped in a new NodeList:
// | var node = l[3]; // the 4th element
// | var newList = l.at(1, 3); // the 2nd and 4th elements
// example:
// the style functions you expect are all there too:
// | // style() as a getter...
// | var borders = dojo.query(".thinger").style("border");
// | // ...and as a setter:
// | dojo.query(".thinger").style("border", "1px solid black");
// | // class manipulation
// | dojo.query("li:nth-child(even)").addClass("even");
// | // even getting the coordinates of all the items
// | var coords = dojo.query(".thinger").coords();
// example:
// DOM manipulation functions from the dojo.* namespace area also
// available:
// | // remove all of the elements in the list from their
// | // parents (akin to "deleting" them from the document)
// | dojo.query(".thinger").orphan();
// | // place all elements in the list at the front of #foo
// | dojo.query(".thinger").place("foo", "first");
// example:
// Event handling couldn't be easier. `dojo.connect` is mapped in,
// and shortcut handlers are provided for most DOM events:
// | // like dojo.connect(), but with implicit scope
// | dojo.query("li").connect("onclick", console, "log");
// |
// | // many common event handlers are already available directly:
// | dojo.query("li").onclick(console, "log");
// | var toggleHovered = dojo.hitch(dojo, "toggleClass", "hovered");
// | dojo.query("p")
// | .onmouseenter(toggleHovered)
// | .onmouseleave(toggleHovered);
// example:
// chainability is a key advantage of NodeLists:
// | dojo.query(".thinger")
// | .onclick(function(e){ /* ... */ })
// | .at(1, 3, 8) // get a subset
// | .style("padding", "5px")
// | .forEach(console.log);

// If a string, a single-expression CSS rule. For example,
// ".thinger" or "#someId[attrName='value']" but not "div >
// span". In short, anything which does not invoke a descent
// to evaluate but can instead be used to test a single node
// is acceptable.
// example:
// "regular" JS filter syntax as exposed in dojo.filter:
// | dojo.query("*").filter(function(item){
// | // highlight every paragraph
// | return (item.nodeName == "p");
// | }).style("backgroundColor", "yellow");

// description:
// a copy of the HTML content is added to each item in the
// list, with an optional position argument. If no position
// argument is provided, the content is appended to the end of
// each item.
// content:
// DOM node, HTML in string format, a NodeList or an Object. If a DOM node or
// NodeList, the content will be cloned if the current NodeList has more than one
// element. Only the DOM nodes are cloned, no event handlers. If it is an Object,
// it should be an object with at "template" String property that has the HTML string
// to insert. If dojo.string has already been dojo.required, then dojo.string.substitute
// will be used on the "template" to generate the final HTML string. Other allowed
// properties on the object are: "parse" if the HTML
// string should be parsed for widgets (dojo.require("dojo.parser") to get that
// option to work), and "templateFunc" if a template function besides dojo.string.substitute
// should be used to transform the "template".
// position:
// can be one of:
// | "last"||"end" (default)
// | "first||"start"
// | "before"
// | "after"
// | "replace" (replaces nodes in this NodeList with new content)
// | "only" (removes other children of the nodes so new content is hte only child)
// or an offset in the childNodes property
// example:
// appends content to the end if the position is ommitted
// | dojo.query("h3 > p").addContent("hey there!");
// example:
// add something to the front of each element that has a
// "thinger" property:
// | dojo.query("[thinger]").addContent("...", "first");
// example:
// adds a header before each element of the list
// | dojo.query(".note").addContent("<h4>NOTE:</h4>", "before");
// example:
// add a clone of a DOM node to the end of every element in
// the list, removing it from its existing parent.
// | dojo.query(".note").addContent(dojo.byId("foo"));
// example:
// Append nodes from a templatized string.
// dojo.require("dojo.string");
// dojo.query(".note").addContent({
// template: '<b>${id}: </b><span>${name}</span>',
// id: "user332",
