Better Loading UI Story

[dOrgJelli]

Currently, loading stops itself at the top of the tree, which disables the rendering of all encapsulated UI elements.

Ideally, if a view is trying to use DAO information within a view, the entirety of the view would render, and only the data fields that're tied to the DAO's query to the graph server would have a loading bar. Currently this whole view would be a loading bar. Create some test cases for this, ensure it is in fact "broken", and figure out a better strategy for developers.

The work on this is currently happening in this branch:

This needs testing once we have an example app.
