Sample app for existing TODO client

[aboodman]

We have an ancient (~6 months) Flutter client that @sboodman and I wrote which implements a pretty nice little TODO list.

It was written against the old Replicant v1 design.

We want to update this to be a sample for Replicache. In order to do that, we need a backend that implements the features required by the client.

I'm thinking:

• Golang (because we already use it and why add a new language)
• Heroku (because we need an easy backend somewhere with persistence, and heroku is super popular, so a good sample for us)
• Postgres (again, super popular, good sample)

The backend is a simple JSON API, with some kind of authentication (google? email? what's easiest) having the following features:

• /list/create() => listID
• /list/list() => []TodoList
• /list/share(emailAddress)
• /list/delete(listID)
• /todo/create(listID, name, description, position, done) => todoID
• /todo/list(listID)
• /todo/complete(todoID, done)
• /todo/reorder(id, position)
• /todo/delete(id)

This exists enough to create smaller bugs for remainder. 🍾
