        EVENTS AND THEIR PARAMETERS.

        redstone: Returns NO parameters.
        modem_message:
                        * param1: string side
                        * param2: number frequency
                        * param3: number replyFrequency
                        * param4: message
                        * param5: number distance travelled
                        - a good way to detect from where the modem message came from is by checking the replyFrequency.
        rednet_message:
                        * param1: number senderID
                        * param2: message
                        * param3: protocol/message travelled
