Allow re-use of components in templates

[bgantzler]

This is NOT intended to be a merged request, but to give you an example of what you might do. I created a component called named-components and using hash and yeild allow the re-use of the same component multiple times in the same template. Look at the models-table.hbs for use of the named-component. Figured it would make your templates easier to maintain.

@bgantzler, thanks for idea. I believe into this RFC emberjs/rfcs#200 and hope it will be implemented. Currently I'm thinking about with-usage. Actually I'm thinking about two things. First one - should I use with to refactor templates? Second one - how I missed with for such long time?

I knew about the RFC, but since it wasnt done yet, thought this would work. I used with a long time ago, people were over using it, and it led to problems. I should have checked it again before I created this because it looks like I just recreated with :)

Yes, I think you should use with in this case. Its backward compatible and available now.
