The Aim

Implement the cost reporting

You are provided with a base code that loads the data, and can produce, on demand, a report of time spent.

1. Your mission, if you accept it, it to edit this function and add a column containing the costs.
2. Mission 2: add a Gaussian companion to the remuneration time-series. Print min/max/avg/std in logs
3. Mission 3: add a new API to display this information in the front.

Starting it all

1. Install GreyCat https://get.greycat.io. Test gregcat -v displays the version.
2. Install NPM or PNPM (ask google)
3. Install and open VSCode at the root folder ot the project
4. Install GreyCat plugin for VSCode if not already available
5. In VSCode open a terminal, run greycat serve
6. In a second terminal, run pnpm i to install web dependencies
7. Run pnpm run gen to generate the TypeScript GreyCat SDK for this project
8. Run pnpm run dev to serve the web-application in development mode
9. Play a bit, browse, search, understand, add the features
10. On demand, when necessary, restart the backend (ctrl+c && greycat serve) to reload the behavior
