Backend: write the main function of the simulation that generates all…

… of the values the simulaion needs. + finish writing the order rooms algorithm for the simulation.

I go over the algorithm for order rooms in the simulation and add option for a user to add another users in the simulation. In addition, I wrote the main function that calls all the functions that generate random values for the simulation.
