对GWT的jQuery的克隆，以及更多。

**IMPORTANT: GwtQuery has been moved to github, please report issues, ask request features or contribute to code there: http://github.com/gwtquery** Introduction GwtQuery a.k.a. GQuery is a jQuery-like API written in GWT, which allows GWT to be used in progressive enhancement scenarios where perhaps GWT widgets are too heavyweight. It can also be used to complement your normal GWT development giving you powerful tools which are not present in GWT-core: find and enhance your GWT widgets, promote dom elements to widgets, decouple UI parts, useful methods to access js functions and properties without writing jsni, Promises and much more. GwtQuery is easy to learn for those using jQuery as they share the same api, aditionally gquery adds nice features like type-safe css, compile time optimisations, etc. Currently, almost the jQuery API is written and all CSS3 selectors should be supported.
