This is a client-side event bus based on the portable push library [Atmosphere|https://github.com/Atmosphere/atmosphere]that propagates events from the server-side event bus provided by the [Platform Core|http://grails.org/plugin/platform-core]to the browser. It allows your client Javascript code to both send events and listen for them. For security, events-push is a white-list broadcaster so that you can control exactly which events are propagated fromthe server to the browser.
