[amyrlam]

WIP

Resolves: #285

[amyrlam]

@locks here is my WIP to help with async help. if you or others have any ideas on how to further debug, please lmk!

• package contents (subpackages?) don't appear at all

IS:

master:

• have 7 test failures, most with the TypeError: Cannot read property 'split' of undefined error, but lost on how to debug

//

• initially wanted to just add a redirect modules to packages, ended up not quite working, so went for the full thing
• as is, was a little unsure of how to handle the transitionTo since wasn't a straightforward beforeModel
• removed headless chrome for debugging purposes only
• just saw the merge conflicts, can address later
• git history here was more for my own purposes, would be cleaned up ofc

I think you need a custom serializer to map things in the payload named "module" or variations of it to the appropriate fields in Ember Data where it's named package.
