Passing context or metadata into component cards/atoms #82
Description
I'd like to be able to pass some arbitrary metadata about a mobiledoc down into the Ember components that render cards and/or atoms. Is there any good way to do this at the moment?
Here's a use case: I have some metadata about a mobiledoc's author. I'd like to refer to this in building the payload for certain atoms.
At the moment, it seems to me that the only way to do this is to subclass the mobiledoc-editor component and write a custom template that passes in the additional properties here. That doesn't seem optimal to me, because there's no way to inherit a parent template and override only a subsection thereof. Among other things, it's hard for maintainability; every time the component template changed upstream, consumers would have to manually review changes to the code upstream and update...
I understand if you don't want unnecessary clutter in the code, but I think it would be quite helpful to provide some way for consumers to pass context into their atom/card components. Any suggestions? (I'd be happy to provide a PR if appropriate.)
