/**
* jqMobi is a query selector class for HTML5 mobile apps on a WebkitBrowser.
* Since most mobile devices (Android, iOS, webOS) use a WebKit browser, you only need to target one browser.
* We are able to increase the speed greatly by removing support for legacy desktop browsers and taking advantage of browser features, like native JSON parsing and querySelectorAll
