/*
* 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.
