+	dojo.query() architectural overview:
+
+		dojo.query is a relatively full-featured CSS3 query library. It is
+		designed to take any valid CSS3 selector and return the nodes matching
+		the selector. To do this quickly, it processes queries in several
+		steps, applying caching where profitable.
+		
+		The steps (roughly in reverse order of the way they appear in the code):
+			1.) check to see if we already have a "query dispatcher"
+				- if so, use that with the given parameterization. Skip to step 4.
+			2.) attempt to determine which branch to dispatch the query to:
+				- JS (optimized DOM iteration)
+				- native (FF3.1+, Safari 3.1+, IE 8+)
+			3.) tokenize and convert to executable "query dispatcher"
+				- this is where the lion's share of the complexity in the
+				  system lies. In the DOM version, the query dispatcher is
+				  assembled as a chain of "yes/no" test functions pertaining to
+				  a section of a simple query statement (".blah:nth-child(odd)"
+				  but not "div div", which is 2 simple statements). Individual
+				  statement dispatchers are cached (to prevent re-definition)
+				  as are entire dispatch chains (to make re-execution of the
+				  same query fast)
+			4.) the resulting query dispatcher is called in the passed scope
+			    (by default the top-level document)
+				- for DOM queries, this results in a recursive, top-down
+				  evaluation of nodes based on each simple query section
+				- for native implementations, this may mean working around spec
+				  bugs. So be it.
+			5.) matched nodes are pruned to ensure they are unique (if necessary)

+		//		instead of using a brittle and slow regex-based CSS parser,
+		//		dojo.query implements an AST-style query representation. This
+		//		representation is only generated once per query. For example,
+		//		the same query run multiple times or under different root nodes
+		//		does not re-parse the selector expression but instead uses the
+		//		cached data structure. The state machine implemented here
+		//		terminates on the last " " (space) charachter and returns an
+		//		ordered array of query component structures (or "parts"). Each
+		//		part represents an operator or a simple CSS filtering
+		//		expression. The structure for parts is documented in the code
+		//		below.
+
+
+		// NOTE: 
+		//		this code is designed to run fast and compress well. Sacrifices
+		//		to readibility and maintainability have been made.  Your best
+		//		bet when hacking the tokenizer is to put The Donnas on *really*
+		//		loud (may we recommend their "Spend The Night" release?) and

+		//			* `+`, the preceeded-by sibling selector
+		//			* attribute queries:
+		//			|	* `[foo]` attribute presence selector
+		//			|	* `[foo='bar']` attribute value exact match
+		//			|	* `[foo~='bar']` attribute value list item match
+		//			|	* `[foo^='bar']` attribute start match
+		//			|	* `[foo$='bar']` attribute end match
+		//			|	* `[foo*='bar']` attribute substring match
+		//			* `:first-child`, `:last-child`, and `:only-child` positional selectors
+		//			* `:empty` content emtpy selector
+		//			* `:checked` pseudo selector
+		//			* `:nth-child(n)`, `:nth-child(2n+1)` style positional calculations
+		//			* `:nth-child(even)`, `:nth-child(odd)` positional selectors
+		//			* `:not(...)` negation pseudo selectors
+		//
+		//		Any legal combination of these selectors will work with
+		//		`dojo.query()`, including compound selectors ("," delimited).
+		//		Very complex and useful searches can be constructed with this
+		//		palette of selectors and when combined with functions for
+		//		manipulation presented by dojo.NodeList, many types of DOM
+		//		manipulation operations become very straightforward.
+		//		
+		//		Unsupported Selectors:
+		//		----------------------
+		//
+		//		While dojo.query handles many CSS3 selectors, some fall outside of
+		//		what's resaonable for a programmatic node querying engine to
+		//		handle. Currently unsupported selectors include:
+		//		
+		//			* namespace-differentiated selectors of any form
+		//			* all `::` pseduo-element selectors
+		//			* certain pseduo-selectors which don't get a lot of day-to-day use:
+		//			|	* `:root`, `:lang()`, `:target`, `:focus`
+		//			* all visual and state selectors:
+		//			|	* `:root`, `:active`, `:hover`, `:visisted`, `:link`,
+		//				  `:enabled`, `:disabled`
+		//			* `:*-of-type` pseudo selectors
+		//		
+		//		dojo.query and XML Documents:
+		//		-----------------------------
+		//		
+		//		`dojo.query` (as of dojo 1.2) supports searching XML documents
+		//		in a case-sensitive manner. If an HTML document is served with
+		//		a doctype that forces case-sensitivity (e.g., XHTML 1.1
+		//		Strict), dojo.query() will detect this and "do the right
+		//		thing". Case sensitivity is dependent upon the document being
+		//		searched and not the query used. It is therefore possible to
+		//		use case-sensitive queries on strict sub-documents (iframes,
+		//		etc.) or XML documents while still assuming case-insensitivity
+		//		for a host/root document.
+		//
+		//		Non-selector Queries:
+		//		---------------------
+		//
+		//		If something other than a String is passed for the query,
+		//		`dojo.query` will return a new `dojo.NodeList` instance
+		//		constructed from that parameter alone and all further
+		//		processing will stop. This means that if you have a reference
+		//		to a node or NodeList, you can quickly construct a new NodeList
+		//		from the original by calling `dojo.query(node)` or
+		//		`dojo.query(list)`.
+		//
+		//	query:
+		//		The CSS3 expression to match against. For details on the syntax of
+		//		CSS3 selectors, see <http://www.w3.org/TR/css3-selectors/#selectors>
+		//	root:
+		//		A DOMNode (or node id) to scope the search from. Optional.
+		//	returns: dojo.NodeList
+		//		An instance of `dojo.NodeList`. Many methods are available on
+		//		NodeLists for searching, iterating, manipulating, and handling
+		//		events on the matched nodes in the returned list.
+		//	example:
+		//		search the entire document for elements with the class "foo":
+		//	|	dojo.query(".foo");
+		//		these elements will match:
+		//	|	<span class="foo"></span>
+		//	|	<span class="foo bar"></span>
+		//	|	<p class="thud foo"></p>
+		//	example:
+		//		search the entire document for elements with the classes "foo" *and* "bar":
+		//	|	dojo.query(".foo.bar");
+		//		these elements will match:
+		//	|	<span class="foo bar"></span>
+		//		while these will not:
+		//	|	<span class="foo"></span>
+		//	|	<p class="thud foo"></p>
+		//	example:
+		//		find `<span>` elements which are descendants of paragraphs and
+		//		which have a "highlighted" class:
+		//	|	dojo.query("p span.highlighted");
+		//		the innermost span in this fragment matches:
+		//	|	<p class="foo">
+		//	|		<span>...
+		//	|			<span class="highlighted foo bar">...</span>
+		//	|		</span>
+		//	|	</p>
+		//	example:
+		//		set an "odd" class on all odd table rows inside of the table
+		//		`#tabular_data`, using the `>` (direct child) selector to avoid
+		//		affecting any nested tables:
+		//	|	dojo.query("#tabular_data > tbody > tr:nth-child(odd)").addClass("odd");
+		//	example:
+		//		remove all elements with the class "error" from the document
+		//		and store them in a list:
+		//	|	var errors = dojo.query(".error").orphan();
+		//	example:
+		//		add an onclick handler to every submit button in the document
+		//		which causes the form to be sent via Ajax instead:
+		//	|	dojo.query("input[type='submit']").onclick(function(e){
+		//	|		dojo.stopEvent(e); // prevent sending the form
+		//	|		var btn = e.target;
+		//	|		dojo.xhrPost({
+		//	|			form: btn.form,
+		//	|			load: function(data){
+		//	|				// replace the form with the response
+		//	|				var div = dojo.doc.createElement("div");
+		//	|				dojo.place(div, btn.form, "after");
+		//	|				div.innerHTML = data;
+		//	|				dojo.style(btn.form, "display", "none");
+		//	|			}
+		//	|		});
+		//	|	});
+
+		//Set list constructor to desired value. This can change
+		//between calls, so always re-assign here.
