Sketch ideas for YNAB integration

The end goal is to have some functions that help me manage my Monzo and YNAB
accounts. YNAB (i.e. youneedabudget.com) doesn't support Monzo
integrations. However, both services offer APIs. Here I'm sketching ideas for
what the API integrations might look like. Coming soon: monzo.el.
