new method canAcceptEntity added to MachineManagedJob. This method checks whether a machine can receive a specific entity

If the operationType is only Load, the Machine clears the activeCallersList of the operator when the operator is released. Otherwise the activeCallersList is cleared byt getEntity of Machine regardles of the type of the Machine.

operatorAssignedTo attribute collapsed to operator. checkIfResourceIsAvailable of OperatorPreemptive removed as redundant

OperatorPool will check if any operator can preempt when there no operators available. checkIfResourceCanPreempt added to OperatorPool. checkIfResourceCanPreempt of OperatorPreemptive preemts the currentStation if there is such need

additional control before preemption. The object must be Up before any attempt for preemption is performed

new method checkIfResourceCanPreempt added to objectResource. The method will check weather the object currently occupying the resource can be preempted and if there is need will eventually preempt the object.

CoreObject getEntity now checks if the receiver is operated before performing the preemption. In that case the preemption must be performed by the operator
