You will be given a json file containing details about a number of locations grouped by their latitude and longitudes.

Within the location details is information about the count of places nearby the location that match a specific category, and the weighting of importance of that category, between 0 - 1.

You will also be given information about the user's preference, and a description of each location. Take this into consideration when generating scores.

Generate a location suitability score taking these into account for each location. The score should be between 1 - 5 inclusive, to two decimal places. The minimum score a location can receive is 1.
