Create login view

[samchurney]

We need a view to greet the user if they have not yet been authenticated.

The designs can be found here

Note: Functionality to authenticate the user via the API will come later. Create UI only for now and set "Log In" button to navigate to Home view.

@samchurney I'm not able to view the InVision link. Could I get an invite? Thanks

[samchurney]

Sure! Sent an invite :)

[darecstowell]

Got it. Thanks!

If we're still going to use the React Semantic UI component library, this could be a good starting point: https://react.semantic-ui.com/layouts/login

Copy/Pasted it to the "Semantic Examples" view on the semantic-ui branch (PR #11) in case you want to pull down that branch and have an easy way of seeing it in action/modifying it.

@darecstowell Would you be able to work on the initial auth flow in this issue? For example, when we first start the app, we should determine whether the user has been authenticated with the API (functionality will come later). Maybe we could have the user be unauthenticated until they enter anything into the login form at which point we can authenticate them (just to get the flow working).

@samchurney oops just now seeing this! I need to update my notifications on here. Yes, I can work on some basic auth things on this page to get us going. And thanks @ahaurat ! That's a super helpful starting point.
