#Esta tarea permite copiar stands de un evento a otro evento, INCLUYENDO LA RESERVA.
#Normalmente la piden para copiar los stands de un antiguo evento de camacol a otro mas reciente.
#Despues de correr la tarea si hubo algun fallo este se guardara en track_errors(Array)
#OJO: Esta tarea no es trasaccional.
