+// UDPSocketLibevent
+// Accessor API for a UDP socket in either client or server form.
+//
+// Client form:
+// In this case, we're connecting to a specific server, so the client will
+// usually use:
+//       Connect(address)    // Connect to a UDP server
+//       Read/Write          // Reads/Writes all go to a single destination
+//
+// Server form:
+// In this case, we want to read/write to many clients which are connecting
+// to this server.  First the server 'binds' to an addres, then we read from
+// clients and write responses to them.
+// Example:
+//       Bind(address/port)  // Binds to port for reading from clients
+//       RecvFrom/SendTo     // Each read can come from a different client
+//                           // Writes need to be directed to a specific
+//                           // address.
