Avaza CLI tool

Using Avaza? With this tool you can update your hour registration, and receipts from the CLI.

Development notes

• Assumes >= Go 1.11
• I use Nix to define the build environment; just run nix-shell.
• Uses go-swagger to generate the client from the Swagger/Open-API spec of Avaza. Please run ./tools/gen-code.sh to both download the swagger spec and generate the client from it.
