Create one demo day slide

[luccalb]

As part of the homework in Sprint 13, we should create one demo day slide

Create one demo day slide and upload to Deliverables folder
Make it a landscape PDF of proportions 16:9 (screen size)
Name and upload file to sprint-1y/demo-day-slide.pdf

Demo day slide
Create one overview slide of your project for inclusion in the demo day introduction.
This can be sparse: Project idea, a screenshot, team photo, logo. (Real content is in demos.)
This is not necessarily the slides you may use at your demo; in your demo you can use others.
