Mediator.cpp

/**
 * @cite Mediator Pattern states that in order to establish communication between multiple components, a central component(mediator) should be set up so that the components don't have to directly interact with each other.
 * Aims at promoting modularization by decoupling all the components from each other.
 *
 * @brief Mediator Pattern can be exemplified by an Online Game that needs multiple players to interact with each other.
 * It can be done using a Server as a mediator that keeps references to all the players.
