Week 1, getting set up

[matentzn]

• [x] Do a number of FastAPI tutorials and create a markdown page "Getting started with FastAPI development" with the stuff you found most useful (we will add this to obook)
• [x] Create a basic layout for this repo here that involves a (non-functional) endpoint, basic testing and a swagger UI. We want to be really careful to build a perfectly crafted API with minimal code to convince the SPOT team its better for them moving forward.
• [x] Get set up for oak development in your local environment (just being able to build it and run tests, for now, is enough).
