A utility library for messaging between iframes and their container.

Basic Use

Listeing for events in an iframe:

transit.on('EventName', function (event, data) {
    console.log(data); //messageObject
});

Broadcasting to the container from the iframe:

transit.broadcast('EventName', messageObject, window.parent);

Listening for iframe messages

transit.on('EventName', function (event, data) {
    console.log(data); //messageObject
});
