+ * Optional limited selector module for custom builds.
+ *
+ * Note that this DOES NOT SUPPORT many documented jQuery
+ * features in exchange for its smaller size:
+ *
+ * * Attribute not equal selector (!=)
+ * * Positional selectors (:first; :eq(n); :odd; etc.)
+ * * Type selectors (:input; :checkbox; :button; etc.)
+ * * State-based selectors (:animated; :visible; :hidden; etc.)
+ * * :has(selector)
+ * * :not(complex selector)
+ * * custom selectors via jQuery extensions
+ * * Leading combinators (e.g., $collection.find("> *"))
+ * * Reliable functionality on XML fragments
+ * * Requiring all parts of a selector to match elements under context
+ *     (e.g., $div.find("div > *") now matches children of $div)
+ * * Matching against non-elements
+ * * Reliable sorting of disconnected nodes
+ * * querySelectorAll bug fixes (e.g., unreliable :focus on WebKit)
+ *
+ * If any of these are unacceptable tradeoffs, either use the full
+ * selector engine or  customize this stub for the project's specific
+ * needs.
