Create Day 9 or 10 materials that bring it all together

[ryoliver]

It would be great to create materials for the final two days that bring everything together, especially showing them how the key skills we built integrate into an overall workflow.

I could envision this as:

1. a lecture that articulates how each piece would fit into a project
2. a GitHub repository for an example project that brings everything together
3. some sort of activity that asks them to modify/update this repo
