+Hanley README for Multicast Homework
+
+Modified the code from multicast example 1.
+
+- adjusted packet to get compiled for every send
+- computed the "position" of the entity for each packet
+- shout out to Chris A for identifying the need to change the receiver to listen for doubles and not floats
+
+
