/*
* Optional (non-Sizzle) 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 Sizzle 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 Sizzle or
* customize this stub for the project's specific needs.
