Romain CLEMENT fad41c80b3 Put attendant thread in background 
This allow main thread to terminate without any error when each
car thread has terminated.
It's more accurate, because otherwise the attendant will wait
forever and block the program.

The Barbershop problem

Introduction

The original barbershop problem was proposed by Dijkstra. A variation of it appears in Silberschatz and Galvin’s Operating Systems Concepts.

A barbershop consists of a waiting room with n chairs, and the barber room containing the barber chair. If there are no customers to be served, the barber goes to sleep. If a customer enters the barbershop and all chairs are occupied, then the customer leaves the shop. If the barber is busy, but chairs are available, then the customer sits in one of the free chairs. If the barber is asleep, the customer wakes up the barber. Write a program to coordinate the barber and the customers.

Purpose

The purpose of this project is to implement a semaphore from the little book of semaphores for the school subject R.5.A.10.
