## shopping_mall
### Instructions
Using the `mall` module provided, create the following **functions** to help run a shopping mall:
- `biggest_store` : receives a `Mall` and returns the `Store` with the biggest `square_meters` .
- `highest_paid_employee` : receives a `Mall` and returns a vector containing the `Employee` (s) with the highest salary.
- `nbr_of_employees` : receives a `Mall` and returns the number of employees and guards as a `usize` .
- `check_for_securities` : receives a `Mall` and a vector of `Guard` . If there is not at least 1 guard for every 200 square meters of floor size, a guard should be added to the `Mall.guards` .
- `cut_or_raise` : receives a `Mall` . For each employee, the salary will be raised by 10% if they work more than 10 hours, else their salary will be decreased by 10%. You can consider that guards are not employees of the mall.
### Expected Function
> You'll need to work out the function signatures for yourself.
