signalReceiver corrected. Controls if the receiver has to be loaded or setup before signalling the router

signalReceiver of QueueManagedJob now sorts for the operator assigned to the Receiver the Queue before signalling

appendEntity method adds newly created entities to G.pendingEntities and warms them according to the status of the next stations

machine checkOperator method checks if the machine is assigned an operator. assignedOperator flag informs if the machine has already an operator assigned

SignalReceiver of QueueManagedJob modified to handle signalling of the Router in case there is conflict between different Machines competing for the same Resource

assignTo/unAssign/isAssignedTo methods of managed operator moved to simple operator. sortCandidateEntities method of simple operator sorts candidate stations. ToBe reviewed and renamed

Broker calls directly Router. Operated machines now signalled by the Router whenever a resource is made available

MachineManagedJob minor corrections. CheckOperator corrected, managedJob operator checkIfResourceIsAvailable should have caller

signalGiver/Receiver update .giver/receiver variable only before sending the signal to the receiver/giver

Exit object has its own haveToDispose which always returns False. Other minor corrections to Machines and OperatedPoolBroker

new methods that block the entry of an object. Implemented on machines to avoid receiving to signals at the same simulation time

Machine now communicates with Broker via events. Machine waits for isRequested signal to getEntity. Can also get an entity after a loadOperatorAvailable event in case it could not getEntity due to resources lack
