RrMultiUserScheduler is a simple OFDMA scheduler that indicates to perform a DL OFDMA transmission if the AP has frames to transmit to at least one station.
RrMultiUserScheduler assigns RUs of equal size (in terms of tones) to stations to which the AP has frames to transmit belonging to the AC who gained access to the channel or higher. The maximum number of stations that can be granted an RU is configurable. Associated stations are served based on their priority. The priority is determined by the credits/debits a station gets when it is selected or not for transmission.

Destructor implementation.
This method is called by Dispose() or by the Object's destructor, whichever comes first.
Subclasses are expected to implement their real destruction code in an overridden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.
It is safe to call GetObject() from within this method.

Initialize() implementation.
