title: Meteor: store object in rendered() to be used in child helpers
body: <p>I would like to store an object that I create during <code>Template.myTemplate.rendered = function ( ) { ... }</code> and use that object in <code>Template.myChildTemplate.helpers(helpers)</code>. So far I'm resorting to using a global object, but that feels very hacky. Is there a nice Template-centric way of doing this?</p>
