For custom protocol buffer data, create a proto file in the folder protobuf_files and run the script generate_proto_files
This will output your custom protocol buffer into the package src.main.java.protobuf
You can create custom Client and Server data handler classes that extend the protobuffer type you just created to use
Using ClientDataHandler and ServerDataHandler as examples
protobufauditor.proto generates JdssAuditor.java. A custom protocol I will be using to send messages to BART platform signs
