        public PossibleValuesService​(InterMineAPI im)
        A service for providing column summary information. This information is designed to be used in forms that provide autocomplete or drop-down options to suggest possible values. It expects a path (such as Employee.name, or CEO.company.departments.employees.name), and lists all possible values that path may represent, along with their frequency. The values list is sorted by the value, not the frequency.
        Parameters:
        im - A reference to the InterMine API bundle.
