Used to send and receive data using the UDPSocket class.
A Datagram consists of two parts, the IP address of the remote machine which sent you the data, and the data itself. When you attempt to send data, you must specify information in the form of a Datagram. This information is usually the remote address of the machine you want to receive your packet, the port it should be sent to, and the data you wish to send the remote machine. Please see the UDPSocket for information on how to use the Datagram.
