Nix flake for an example haskell package

To get started:

• In the package.yaml, set any names beginning with example to your chosen name - for example, change the name setting on the first line from example-package to the nameof your new package.
• Run hpack from the terminal; this will generate a cabal file for your project.
• Run cabal test or cabal run ${executable-name}, where ${executable-name} is the name of your executable, defined under executables in the package.yaml.

Overview of what's here This flake has a simple executable, a library that that executable depends on, and a test suite which tests the library.

It uses cabal to build, hpack as the format for the cabal project specification, and hspec to run tests.

Remember to run hpack after any changes to the package.yaml, in order to re-create the ${project-name}.cabal file, as well as the first time you try to use this.

The executable can be run via cabal using cabal run example-executable, whereas tests can be run via cabal test.
