+Final Project Notes:
+
+We constructed code to communicate between parties via DIS over a LAN (Local Area Network).
+The PDU and Espdu example files were the genesis of the two files.
+
+To run our code you need to open two main classes
+    C_T_EspduRequestingUnit.java, and C_T_EspduSupplyingUnit.java
+
+In order to get the program to run properly, execute:
+First: C_T_EspduSupplyingUnit.java
+Next:  C_T_EspduRequestingUnit.java
+
+Each class has the capability to both sender and receive packages. They are listening 
+for specific types of PDU packets, and will then send a response accordingly. 
+
+Below is the output from running the code-
