    """ Provides for (integer) values within defined ranges to provide
        equal or similar output.

        For example:

            Suppose one is running a tournament and has a $5000 prize for first
        place, $1000 prizes for second through fourth place, and $500 prizes
        for fifth through eigth place.
            Instead of creating an array/hash table to associate /each/ place
        with a cash prize, or using an if block to painstakingly hardcode the
        values, what one really wants is for a certain *range* of numbers to
        be associated with a certain value.
            Which is what this class is for.
