EventHub is a small, simple, well...uh, event manager. It does not support DOM events. It is intended to be used as a notification center for an application or to add event management behaviors to other objects. It is similar to jQuery in use. For instance, obj.on('foo bar', some_fn) will call some_fn when either "foo" or "bar" are fired on obj.
Have a look at the unit tests for usage examples.
You can install using bower
bower install eventhub.js
Eventhub will register itself using AMD, Node and/or AngularJS. If none of those environments are found it will be available as a global. If you are using angular, depend on the eventhub module and inject the EventHub class.
