Specification: A class for counting the number of people in a room. This might be used to control how many people are allowed into a club with a doorman.

Suppose that you are going to create an object used to count the number of people in a room. We know that the number of people in the room can never be negative. Create a RoomCounterclass having three public methods:

addPerson -- adds one person to the room
removePerson -- removes one person from the room
getCount -- returns the number of people in the room

If removePerson would make the number of people less than zero, throw a NegativeCounterException.
