Create use case examples

[victorb]

In order to show what Instant Website can be used for, it'd be great to have bunch of example websites created with Instant Website.

I've created a couple of issues that can all be worked on independently, and once they are created we can link them from the Instant Website website.

The basic idea here is that we create independent websites for each one of these that showcase how Instant Website can be used. So for the documentation use case, we create an example website that could act as a base documentation website.

Current issues:

• Landing Page Use Case Example: Landing Page #11
• Documentation Use Case Example: Documentation #12
• Portfolio Use Case Example: Portfolio #13
• Data Visualization Use Case Example: Data Visualization #14
• Story Use Case Example: Story #15
