Added elSendNReceive.py, a script to test communication with ethernet link devices. Works some of the time.

3 #Type a command to send it to the entire network
4 #Commands send to Ethernet Link devices should start with "^^Id"
5 #Commands sent to the underlying Whozz Calling? whould start with "^^Id-"
