        Allow using e.g. `import '@/sample-module' instead of using relative paths.
        This makes import paths easier to manage, since it keeps you out of
        relative-path-hell (e.g. '../../../../lib/sample-module' turns into '@/sample-module').

        The tsc compiler *does not* convert these to functional paths. This project uses
        `tsc-alias` after compiling (using `npm run build`) to convert after compile.
        Other options include using Babel with the module resolution extension.

        Change these to whatever you like!
        (Note that using a "$" instead of "@" makes it less ambiguous if you are referring
        to a local or npm module.)
