Operations:

	Elevator:	Use people and floor to	initialize the attributes of the object.
	Elevator (int people =0,int floor=0);

	addPerson:	Takes the number of people to be added as an argument and updates the 
				number of people inside the elevator.
	void addPerson(int person_in);
	
	removPerson:Takes the number of people to be removed as an argument and updates 
				the total number of people inside the elevator.
	void removPerson(int person_out);

	moveUp:		Takes the number of floors to go up and updates the position of
				the elevator.
	void moveUp	(int floors_Up);

	moveDwn:	Takes the number of floors to go down and updates the position of
				the elevator.
	void moveDwn(int floors_Dwn);

	writeReport:Give a summary of the current elevator status.
	void writeReport();


Example:
	
	#include <iostream.h>
	#include "Elevator.h"

	int main()
	{
