steam_small.json aangemaakt met de eerste 5 entries, dit is om te testen.
README.md aangepast met de datastructuur die we bij het sorteren gaan gebruiken. in sorting.py is de sorteer algoritme uitgewerkt echter is deze extreem traag. dit moet sneller gemaakt worder. Maar de omzet van json naar geneste tuple werkt

## Data formaat geheugen tabel
|
||||
Om het sorteren makkelijker te maken gaan we de json in een tuple/list opslaan in het geheugen. Het formaat is een tabel
|
||||
achtige structuur. Als voorbeeld de eerste json entry in een tuple.
