Simple usages of protobuf

Build the project:

make

Sample usage of generated code

$ out/basic 
Initial has_type() false
IsInitialized() false
ByteSizeLong() 0
set_type() called, now has_type() true
IsInitialized() false
ByteSizeLong() 5
...

Serialization/Deserialization with simple client/server programs:

Start the server and wait for the client to connect

$ out/serdes/server

Then start the client from another terminal:

$ out/serdes/client

On the server side, the server should be able to detect the connection from client, and start receiving commands from user.

Received data from unknown client!
Hello Adam
Received <Hello> from Adam
Bye Adam
Client disconected!

There are also the responses from server received by the client:

Type 1, message Unknown
Type 0, message Adam
Type 0, message Adam
Type 0, message Adam

Similarly, for the client side, serdes/py_client/serdes_py_client.py can be used for the same purpose:

$ serdes/py_client/serdes_py_client.py 
readThread received data
type: 1
msg: "Unknown"

readThread received data
type: 0
msg: "Eva"

readThread received data
type: 0
msg: "Eva"

readThread received data
type: 0
msg: "Eva"
