This sets the order of the groups in the network's group array and thus the order in which the groups are updated. This is crucial for standard networks, but less important for continuous networks since continuous networks are updated synchronously.
Any groups not listed in the order will follow those listed, but the previous order of such groups will not be retained. Groups will originally be in the order in which they were created so this command is unnecessary if groups were created in the desired updating order.
For simple recurrent networks, it is important that context groups come before their source group.
